I decided to post this chapter early, since it's still the start of this story. Enjoy.

Sunday afternoon:

Curtain was heading home after going on a walk with Marisol, and their other friend Caroline. Since Caroline was going to leave on a trip for a couple of weeks, Curtain and Marisol wanted to take some time to hang out with her before she left. When it was time for Caroline to go, she headed back to her home and took her car to leave. Marisol and Curtain said their goodbyes, and then they parted ways to their houses since they didn't live too far from one another. They lived in a suburb-like neighbor that was a bridge-drive away from the city, and a walk away from a large park nearby that had lots of trees and land with various assortments of plants.

Curtain returned home that afternoon, and cooked herself some dinner. Afterward, she decided to go into her room while taking a book from her bookcase and taking her backpack with her, since she brought it along when she hung out with Marisol and Caroline. She opened the book, which had to do with plant identification, and then she took out a flower from her backpack. It was a white rose with little yellow diamond shapes on the bottom of the petals.

(While she was with Caroline and Marisol in a park in the city, the two were talking while Curtain heard a voice from behind her. She turned to see a normal tree, but then she heard a female voice say to take the rose behind the tree. Curiosity made Curtain check behind the tree, while suspicious intuition made Curtain cautious. Yet, low and behold, a white rose with little yellow diamonds on the bottom of the petals stood growing behind the tree. Curtain looked at the rose with amazement, since it appeared to be glowing. Then she heard the female voice say to take the rose and to eat one petal. Although Curtain was indeed suspicious of this, she decided to take the mysterious rose anyway, since the voice sounded sincere.)

In her house, Curtain was looking up in her book and online with her laptop any information about this rose, but she found nothing. After taking a moment to think about it, Curtain decided to take a petal and eat it. It tasted sweet, and it seemed to melt away and disappear in her mouth like cotton candy. Although she was surprised by this, Curtain yawned, as she looked at the time to see that it was thirty minutes past ten o'clock. Curtain placed the rose on top of her book as she placed both of them under her bed, and then she turned off her phone and laptop and put them on her lamp-stand. She switched into her pajamas from before, which she cleaned by this time, and tucked herself in to sleep.

Midnight:

Sans returned to the same tree he was hiding in for three days, since no one noticed him there besides a cat which lost one of it's lives when it saw him. He was carrying his scythe, although he held it horizontally with the blade pointing towards the ground. He looked towards Curtain's window and saw that the light was off. He brought something out from his pocket to make sure that he had it, and then he tucked it away, as a dark smile made it's way onto his face.

'Alright. It's time,' Sans thought, and he took a shortcut into Curtain's room.

He quietly teleported into her room, as he stood in front of the window. His eyes quickly scanned the room, and then they rested on Curtain. Sans seemingly glided across the room next to Curtain's bed. Curtain's hair wasn't in a ponytail, and it covered over the top of her pillow, as she slept peacefully on her back. Sans took a moment to look at her face, as he took a slow breath in and out. He sat on the side of her bed, as he took the something, which was a necklace, out from his pocket. He fitted it around his neck, while his scythe stood floating in mid-air, as he hid the heart-shaped glass and golden-bordered locket necklace under his shirt. Then he grabbed his scythe with one hand, as he turned back to Curtain and leaned his face closer to her own.

'It's time to go, Curtain,' Sans thought, as he leaned closer to her while his eyes slowly closed.

He rested his teeth gently on her lips, since that's his way of giving a kiss and he never actually kissed someone before, as he waited for her heart to stop beating.

(Although she tried her best to sleep, Curtain was having a hard time since her stomach felt like it was burning, and she kept hearing the same female voice in her head giving her new information each time she spoke. Then, when the burning and the voice stopped, Curtain was able to relax while laying in bed.

'That flower must be waging war with my stomach, and that voice seems to have speed dial to my head now,' Curtain thought, as she was slowly drifting to sleep.)

A gentle pressure on her lips awoken her, as Curtain picked up her hand to move whatever was on her lips while she opened her eyes. Her eyes widened in surprise to see someone there, as her hand brushed his shoulder, which showed her that he was real. Curtain took her other hand and placed it on his forehead, as Sans opened his eyes in surprise to see that she was awake. With a great amount of strength, Curtain pushed Sans away from her lips and onto the floor, as he landed on his back. She stood up from her bed and looked at the skeleton reaper, as her eyes narrowed. Sans sat up as he rubbed the back of his skull, while moving his hood off of his head. He looked up at Curtain with widened eye-sockets, as Curtain looked at him in confusion. After a momentary stare down, both Curtain and Sans started talking.

Curtain- "What…?"

Sans- "How…?"

Curtain- "Your a… skeleton… Is there a closet in this house I don't know about?"

Sans- "How are you…?"

Curtain- "What in the wor- What are you doing in my room?! Who are you?!"

Sans- "How are you still alive?"

Curtain stood quiet for a moment when Sans asked his question, as she examined him carefully and noticed the scythe that he held in his hand.

"Are you… the Grim Reaper or something?" Curtain asked, nervousness beginning to creep up her arms.

Sans chuckled a bit, as he floated up in mid-air, and then stood on his feet. Curtain was surprised by this, and then Sans replied with a smile and a wink,

"I'm more of a Grin Reaper."

Curtain's eyes narrowed at his pun, while Sans just snickered at her unamused expression. Then Curtain asked,

"What are you doing here…? Am I going to DIE?!"

Curtain became a bit frantic, as Sans lifted the palm of his hand towards her and said,

"No no! Your no where near ready to die yet. Don't panic."

Curtain signed in relief, but then she became suspicious as she asked,

"Then… why are you here?"

Sans stiffened for a moment, unsure if he should answer her question since many replies were coming to his mind at once. Curtain kept a serious expression towards Sans while he took a few extra seconds to sort out his mind. Sans lowered his hand as he tried to reply,

"Uh. Well, you see… I just wanted to see you, and since it's night and not many people are around it's easier for me to travel. I wouldn't want to give people a heart-attack who aren't ready to kick-the-bucket, you know."

Curtain found justification in that response, but she crossed her arms since he still didn't answer her question.

"Why did you come to see me? And while your answering that, who are you?" Curtain asked.

Sans took a moment to respond, as he signed and replied, "My name is Sans. I'm Death."

Curtain took a moment to process this new information, and then she asked, "What? Death? Like Death itself?"

"My Soul is the embodiment of Death, but only half of it. My brother is the other half. We were created because Death is a powerful force that effects all living creatures and balances the World. Since death is inevitable and happens quite often, it's very powerful, and the reason for even taking a form is because if any other embodiment, element, or whatever decided to harness the Soul of Death well… that could be a bad time for basically every living thing in the World," Sans explained, as cool and collective as he naturally was, while Curtain's crossed arms dropped.

"Whoa... That's pretty cool and crazy at the same time… hold on… Why are you telling me ALL of this?" Curtain asked.

Sans grin slightly widened, and he replied, "Because there's a reason why I came here Curtain… I came for you~"

Curtain felt a chill down her spine, as she stared at Sans in surprise for two reasons, and asked,

"Wh-What do you mean? And how do you know my name?"

Sans slowly glided towards Curtain, as she backed away from him onto the wall, while he held a smirk on his face and she felt a little uncomfortable.

"Well Curtain, I've had my eye on you for awhile… at least six months now," Sans said, as he glanced away from her direction, while Curtain's eyes widened.

Sans returned his gaze towards Curtain, as he closed one eye while the other eye revealed a blue glowing iris, while he held a dashing smirk on his face. Curtain felt her cheeks heat up a little under his gaze, but she kept her composure.

"After watching you for so long, and learning about you and your name, I couldn't help but grow more and more fond of you. Your… Your important to me, Curtain. I really… feel something when I see you, and hear you speak…" Sans said, as he stood about two feet in front of her, and reached into his shirt to pull out the glass heart-locket.

Curtain examined the locket with interest, but she was still cautious of Sans, although she felt that he wasn't a threat at the moment. At least that's what she saw of him so far, but considering that he is the embodiment of Death that didn't help her relax at all.

"You see, I had this special locket hand-crafted for the purpose of housing a Soul inside of it, particularly, the Soul of a special lady in my life..." Sans said, as Curtain started putting the pieces together.

"You've mesmerized me Curtain, and… I want to keep you safe, with me. Life is a special thing that all living creatures, humans, and monsters have. I appreciate life more for being able to meet other life-forms, especially you. However, life doesn't last forever, my dear… and… I don't want to lose you..." Sans said, as a look of sadness overcame his facial expression, which made Curtain feel somewhat sorry for the Skeleton Reaper. Sans continued,

"That's why I came here to your room. I have an uncontrollable ability where whatever I touch that is living, dies. So I concluded that, after I touched you, your Soul would be released from your body. Then I would house it in this locket, and be able to keep you with me, forever."

Curtain gasped, and then she said, in a more angry tone, "Whoa whoa whoa! Hold up a second…you tried to kill me to get my Soul into a locket?! What makes you think that I would want to be in a locket for the rest of my quote-on-quote 'life' with you?! I don't even know you! I would never agree to such a thing, no matter how fond you are of me!"

Sans wasn't so surprised by her outburst, as he chuckled while tucking the locket under his shirt.

"Well that's the thing, my dear. I tried to take your life, but instead, I had no effect upon you, which makes no sense," Sans said, as he looked at Curtain, suspiciously.

"Take my life… wait a minute. You wouldn't happen to know someone named… Toriel, do you?" Curtain asked, unsure if she said the name right, as Sans looked at her in shock.

"Ha! You do know her! I knew it! She kept talking to me almost all day today! First I get some weird white rose, then she told me to eat it, and then she kept telling me about how Life and Death balance each other out, and that a life shouldn't be kept prisoner. She told me her name too, and… -Gasp!- She knew..." Curtain said, but then she looked at Sans in surprise of her own revelation.

"She was talking about YOU! She knew you wanted to take my Soul! She must have given me the flower to protect me from you! Oh my gosh, if I ever meet her in person I would give her a freaking hug," Curtain said, and she breathed out in relief.

Sans' mind was racing for various reasons now, and he was quite shocked and upset at the same time since his friend had actually gotten in his way. However, Sans decided to keep his cool for now, as he took a slow breath in and out. Then he thought of something, as he smiled at Curtain, slyly. Curtain noticed his expression, as she looked at him, questionably.

"You know Curtain, I'm certain the flower Toriel gave you can only last for so long to protect you from me. Eventually there won't be anymore of it for you to eat, and she may not be able to give you another one on time… and I happen to be a very patient skeleton and reaper," Sans said, as he took a few steps closer to Curtain, while laying his free-hand on the wall near Curtain's head.

He lifted his scythe to show Curtain her reflection in the blade, as Curtain swallowed hard from nervousness of how close he was and the scythe blade itself. Then Sans said,

"I've seen strong wills such as yours Curtain. Very strong, and when their times were near, they still persevered and lived longer than they were predicted or should have. But it's all the same. All living things will die, new ones will live on, and the cycle repeats. But this time my dear, since you know why I'm here, whenever I have the opportunity, I will take your Soul. No matter where you run, I'll catch up. No matter where you hide, I'll sense your life. I'll hear your heartbeat. You'll be mine eventually."

Curtain looked towards Sans with her eyebrows raised, and then she looked at her reflection in the scythe blade. Seeing her reflection with such a timid and nervous expression on her face, filled Curtain with Determination. Her eyebrows lowered, her eyes slightly narrowed, and her teeth were slightly gritted. Curtain looked up at Sans with determination overcoming her facial expression, as Sans was surprised.

"No! I won't let you take my Soul! You have no right to take my Soul, especially because it's not my time to die! My life should not be kept as a prisoner! Your not getting my Soul for your own selfishness!" Curtain said, with confidence, as Sans became slightly irritated.

"Selfishness, huh? I'm actually giving you the opportunity to see the World and other worlds beyond your wildest dreams. To share my 'life' with you, and yet you think I'm selfish?" Sans asked, calmly.

"Your trying to force me to be with you, and lock my Soul in that locket prison by killing me. Who in the right mind would do that? But what can I expect from the embodiment of Death. That's one prediction that's more obvious than if a one-hundred year old man is going to die," Curtain replied, as Sans let out a small growl while he breathed out.

"Aren't you quite charming, darling? But I guess staying up late makes ladies grow claws," Sans said, as Curtain slightly glared at him.

Then Sans backed away from Curtain by a few steps, and he extended his free-hand towards her, as he said, "There's nothing you can do to change my mind Curtain. Accept your fate, and come with me."

After taking a moment to look at his boney hand, Curtain said, "No. I won't… but maybe..."

Curtain glanced downward, as Sans became curious by what she was about to say and asked, "Maybe…?"

Curtain pursed her lips in thought, and then she looked up at him and said, "How about we make… a deal?"

Sans' eye sparked for half a second, but he kept his composure calm as he lowered his hand, and asked, "What kind of deal?"

Curtain swallowed lightly, and replied, "You want my Soul. I want to keep my Soul. You have a crush on me, and I don't know you. So let's make a deal that would satisfy both of us: You have one month, thirty days, to convince me to let you take my Soul. However, if you can't do so at anytime during the month, then you have to trade a part of your Soul with mine so that I wouldn't have to worry about you killing me again afterward."

Sans was quite surprised and impressed by the deal, and how Curtain was able to think it through in such a short time. After taking a moment to process this, Sans nodded and said,

"That sounds quite fair, but I will like to change one thing."

Curtain held a suspicious expression on her face, and she asked, "What would you change?"

Sans smirked and replied, "Instead of convincing you to come with me, how about you give me a month to make you fall in love with me. That way, if you do, it wouldn't be so bad for you if I take your Soul, and if you don't, then I'll give you a piece of my Soul and leave you alone since there's no mutual feelings. How's that?"

Curtain looked downward in thought, and then she looked back up at Sans and nodded sharply. Sans raised his hand towards Curtain and asked,

"Deal?"

Curtain looked at his hand, and then she grabbed his with her own, as she looked up at Sans and said,

"Deal."

They shook hands, but Sans held firmly onto Curtain's hand and said, "We'll start after sunrise. Oh, and one more thing..."

A string of blue energy wrapped around their hands, as the ends of the string turned golden and each end plunged into Curtain and Sans' forearms. Curtain felt a chill through her arm and body as she saw the string entering her arm, and then it separated into two halves to enter each arm. In place of where the string entered her arm, a symbol drawn in the form of a golden eye glowed in place until it disappeared completely. Curtain released Sans' hand, as she looked at her arm and saw no wound, cut, or even a small incision where the string entered her arm. She looked up at Sans, and she saw that he had the same eye drawn on his radius bone and then it disappeared.

"In case your wondering, when you make a deal with someone like me, and one as serious as this one, the Strings of Completion form and attach themselves to whoever is part of the deal. The Strings of Completion prevent either of us from backing out of the deal, and making us keep our ends of the bargain," Sans said, as he brought up his arm and turned it over when he said 'ends.'

Curtain was still quite shocked, but she nodded in understanding. Sans gave a slight bow to Curtain, and then he pulled up his hood over his head.

"I'll see you later my dear. I look forward to the month ahead. Of course, who knows, it may not be that long~" Sans said in a soothing tone, as he disappeared from the room, leaving a temporary mist of darkness until it completely vanished.

Curtain waited a little while to make sure that Sans was gone. She turned on her lamp and locked the door to her room and locked the window. Then she realized there wasn't a point to lock it since Sans could teleport, but she didn't care. She thought about telling Marisol about her encounter, but she decided not to since she didn't want to make her worry. After taking a moment to breathe in and out slowly, Curtain turned off her lamp and tucked herself in to sleep.

'I'll deal with this later. I have to rest since he's probably coming back in the morning. I must stay strong for a month. That shouldn't be hard since I know his intentions. I'll make it,' Curtain thought, as she drifted back to sleep.
