I am aware Kuon is a high school girl and Sniper Mask is in his 20s. In this story, Kuon is aged up to 22 and Sniper Mask is 26. This takes place years after they escaped the death realm.

Opening her eyes, Kuon saw rays of sunlight hitting the wall. She didn't feel a pair of arms around her, Yuuka wasn't there. She sighed and got up. Sitting at the edge of the bed, Kuon threw her arms up and over her head, stretching. Her back cracked a few times, it didn't hurt her since she did this a hundred times. The door opened. A dark blue-haired man walked in with a smiling mask. His eyes are barely visible. He was wearing a white shirt and black sweatpants. In his hands, a tray with breakfast on it. Kuon smiled.

"Mr. Mask!" she said happily. The man smiled under his mask and walked over to the girl sitting on the bed.

"I told you to call me by my name." The Mask said, giving the girl the tray. Kuon frowned.

"But, 'Mr. mask' sounds cooler! Plus, I forgot your name." the college girl said awkwardly scratching the back of her head. "Hmm, this breakfast looks good! Thanks, Mr. Mask!" she thanked the man and started to eat the meal.

"Thanks, and you're welcome." The man said, "and my name is Makoto Yuuka," he said, staring at Kuon.

"That's a cute name for someone like you!" Kuon smiled. Yuuka's bluish-gray eyes widened under the mask. He blushed and put his hand on one side of his mask.

"Stop it, it's embarrassing…" he muttered embarrassingly. She giggled lightly and continued to eat her breakfast.

After she finished, Kuon stretched her legs and moved them back and forth while Yuuka took the tray away. He came back and started to pick out his work clothes.

"Mr. Mask, I thought you said you didn't work today?" Kuon asked, obviously confused.

"Sorry, I just got a call saying I need to come to work." The man said, still looking for his clothes. "No one is there for work, sorry but I might come home late." Kuon pouted.

"Hmph, you idiot…" She muttered under her breath. Yuuka had his work clothes in his hands, he sighed and walked over. He placed his clothes on the bed and put his fingers on Kuon's chin. Raising her head, their eyes met.

"I'm sorry, Kuon." He apologized. "I promise I'll make it up to you…"

"You better, Mr. Mask," Kuon said, her anger washing away. She could see Yuuka's eyes a little, though the mask still blocked her from seeing him completely.

"I will, when have I broken a promise?"

"Literally yesterday."

"I- okay you're right, I'm sorry," Yuuka muttered. His head down, his hand falling from Kuon's chin. She grabbed that hand quickly, the man's eyes widened, he raised his hand quickly. She smiled softly, her hand going to caress his cheek.

"You're too formal. You don't have to apologize, it wasn't your fault." Kuon whispered softly in a loving tone. Yuuka smiled back and put his large hand over her small one.

"Okay, love, I have to go to work." The masked man said, removing his hand. The blue-haired college girl put her hand down as well. He grabbed his clothes and left for the bathroom.

Minutes later, he came out wearing his work outfit. A black jacket with a white undershirt, an untied tie, black pants, and black dress shoes. He looked embarrassed, but since Kuon couldn't see his face, she didn't know for sure. Yuuka had sweat on his face. He walked until he was over Kuon. He cleared his throat awkwardly.

"K-Kuon…" He murmured very quietly. She laughed slightly.

"You're 26 and you still don't know how to tie your own tie?" Kuon teased.

"B-be quiet!" Yuuka yelled, extremely embarrassed. He cleared his throat again and fixed his posture so his beloved girlfriend could tie his tie. He watched her silently while she went to work, her delicate fingers working with the fabric. He opened his mouth slightly, breathing through his mouth.

"Done!" Kuon said cutely. Was that even possible? He didn't know anymore, she's just too god damn cute for him.

"Ahem, u-uhh thanks, love." He thanked her.

"No problem, Mr. Mask!" Kuon said cheerfully.

While Yuuka got in his car, there was one thing in his mind. How could Kuon be so cheerful? She was even cheerful when they met! And he was about to kill her. He started the car, but he turned around and grabbed something from the back seat.

His sniper…

The masked man sighed. He didn't like killing people anymore. He made a promise to Kuon. Yet, he broke that promise, like every other promise. He just hopes he can keep this recent promise…

It was 2 am. Yuuka has yet to come home. Kuon was sitting on the couch. She had already made dinner, thinking that he would come early. She was completely wrong though…

3 am.

4 am.

5 am.

It was 7 am, Kuon was incredibly tired. Also, incredibly mad. She thought Yuuka would at least fulfill this promise. Though, she was wrong. The sun is already rising up. The blue-haired girl decided to just sleep. Until she heard the door open.

Yuuka walked in. He closed the door and placed his key on the hook near the door. He looked tired. His walking was sluggish, his eyes dropped to half-mast. Kuon ran up to him and hugged him tightly.

"Mr. Mask! I'm so glad your back!" She screamed excitedly. The dark blue-haired man hugged her back.

"Haha, I love you too." The man smiled tiredly.

The girl ended the hug, looked him in the eyes, and slapped him across the face. So hard it left a handprint.

"Kuon…" Yuuka murmured angrily and tiredly. "I don't have time for this, I'm extremely tired…" His hand went to his cheek to try soothing the pain.

"You idiot! I have been waiting for you for hours!" She yelled at him. "I didn't sleep at all!" She fell onto her knees, Yuuka kneeled down to help her. "Y-you b-broke your p-promise…." Kuon said, her voice breaking. She started crying and sobbing. The young man held her in his arms. Kissing her head and soothing her.

"I'm sorry, Kuon," Yuuka whispered to her, his deep voice soothing her. "I didn't mean to break my promise. I'm really sorry…" He kissed her head again. He then picked her up, her hands on his broad chest.

Walking in the bedroom and closing the door with his foot, Yuuka placed Kuon down on the bed, she was already asleep so he tried not to wake her up. She's so beautiful when she's sleeping...the masked man thought. He walked over to the bathroom, his footsteps not making a sound.

He looked at himself in the mirror, his mask off. He looked at the scar under his eye. He raised his hand to touch it. Ouch...it still hurts. He thought. He sighed and started to take off his clothes.

After taking a shower, Yuuka put his mask back on, him using a towel to dry his hair and a towel around his waist. Damn it, I forgot to grab some clothes...The adult man opened the bathroom door, not realizing Kuon was awake. She looked up and blushed in shock.

"M-mr. Mask!" She yelled in shock. He was too tired to do anything, not even getting his clothes.

"Kuon, what time is it?"

"U-umm, 7:40. W-why?" The sniper didn't say anything, he just turned off the bathroom light, dropped his towel, showing all of his glory. The flustered girl laid down fast and turned on her side, her back facing Yuuka. He got in bed and spooned her. She could feel his member touching her leg.

"Good night, my love." He whispered softly in Kuon's ear. And with that, he fell asleep.

"Good night, Yuuka. She said his name softly, going to sleep as well.

Yo, I love this ship so much! I know Yuuka doesn't love Kuon romanticly, but that doesn't stop me from shipping them! The next chapter will be lemon, so be careful 3
