A/N: Hey, guys, thank you so much if you are going to read this. Well, I was just starting to write some TMI fanfics since I've been a writer here but in a different category. I just got this idea from some of the fanfics I've read lately and I just thought that it'll be better if I joined the club in writing stories again. So, I hope you'd enjoy this. The story starts at the night with the party in Alicante.

Summary: "They leave me. Why does everyone I love always leave me?" Jace Lightwood felt alone, now that everyone he knew—everyone he ever loved, had left. "I won't leave you." She reassured, then, he turned to her, "Promise?" "Promise." R&R. Post-CoG. Clace.

Chapter One: First Step to Peace

Fireworks continued exploding into the skies, brightening every darkened part of it.

Luke has just informed them that they're leaving tomorrow night, which made Clary feel like she doesn't want to leave the country sooner. She wanted to feel the peace in the country, for a little longer. She wanted to exploreAlicantewith Jace; she wanted to know what she has to know more about the Shadow World.

However, Clary feels anxious about everything that has happened. Sebastian's body was still missing, not even a trace of it. Magnus had even tried to track him, but it was just impossible. The Clave was still anxious that Jace hadn't really killed Sebastian, that he might be still alive.

Jace looked down at Clary, worriedly and frowned at her. His arms were circling around the curve of her waist. She bit her lower lip and avoided his gaze, knowing things weren't going to be same as it was before. "Something wrong?" Jace asked, with the hint of concern in his voice. He faced her, still waiting for her to look up, but there was no chance.

She deepened her bit into her lips, wanting it to bleed for being stupid. Why would she think that Sebastian might be alive? She shouldn't think things like those for… it might come true. But it is impossible though. This is the man who killed that bastard, standing right in front of her, and Jace always made sure he's dead. "N-nothing." She stuttered, faking a weak smile in her lips.

It was unbearable, Jace could read her eyes—knowing something is wrong, just he couldn't read what is wrong. She looked away, hearing another explosion in the sky. Bright colors spilled into the dark emptied sky and smiled weakly. He did not bother to ask anymore, seeing that she tried to smile even though something is wrong. "Do you want to rest now? It has been an exhausting day, Clary." He sounds so convincing.

She turned, slowly nodding her head and keeping her smile into her lips. He grabbed her hand, interlocked his fingers in between hers and pulled her. She followed him, trying not to be dragged. She giggled, and found herself standing in front of their friends.

Jace smiled widely.

His older brother, Alec, has been clingy into his oblivious gay Sonic the Hedgehog boyfriend—named Magnus Bane, which they met in some party back inBrooklyn. Maybe Alec should thank Clary for that, because if it really wasn't for Clary's problems, he wouldn't have met the warlock.

"Hey, guys, we're just gonna say goodbye right now. Clary's tired." Jace started. Isabelle linked her arm around Simon, who held a glass of drink in his hand and happily looking at the couple.

"Sure thing." Isabelle said. She removed her arm around Simon and pulled Clary into a tight hug. As she pulled away, Clary giggled at her friend's gestures. "Just don't do something stupid."

"If you're talking about us, having—," Jace started but was interrupted by an irritated Clary.

"Are we really gonna talk that here? In the middle of the crowd?" Clary laughed.

Jace snorted at her, linking his arm around her shoulders with their hands still interlocked. He leaned down, kissed her forehead and sighed. He just couldn't believe that after all the things that happened between them; he still got the girl he will only love for the rest of his life.

Then, they turned around and walked away from the crowd.

They hadn't talked since they left the crowd.

Clary kept her fingers together and looked away, nervously. Jace had noticed that she was trying to avoid opening a topic with him, which might lead to something she fears. The anxiety swallowed her heart, fully, without exemption. She even doesn't think Jace wouldn't always be there to protect, neither are Jocelyn, Luke, Alec, Isabelle, Magnus or Simon.

They stopped walking. Clary and Jace arrived in front of Amatis's house. She looked down, hearing her heart hammered inside her ribs and wanting to explode out of her chest. Jace placed a hand on her chin, pulled her face up and stared at her for a moment. "Well, here you are. I'm sure you'd want to sleep now." He leaned down, his hands cupping her cheeky face.

He pulled her into a kiss. He kissed her first. Then, she worked her lips with him. His lips were sweet and passionate, deepening more and more. His hands slid into her arms up into her shoulders and rubbed her neck slowly and pulled her closer. He continued to wrap his lips around her softly, feeling the smoothness of her lips. Clary tasted the bitterness of the drink from the party that Jace had been drinking, but she could care less.

She's kissing the man she loves, for Christ's sake. She loves him, and will absolutely love him forever. There were no distractions tonight, not one for sure. No one would stop them right now—not because they were siblings, not because someone wants to kill them. It was just blissful silence between, as they continued to kiss.

Then, he pulled away. She stared at him, his bright freckled honey eyes shone before hers. He lifted a hand to shove the strand of hair from her eyes so that he will have a better sight in her ecological greenish irises.

She sighed, and forcefully curved her lips into a small smile. "Would you like to come in?" Jace hesitated. What would others think if he did? Hell, he wouldn't care. He wanted to spend their last whole night in Idris with his short hot-headed girlfriend.

"Sure." He agreed. She walked to the door as he followed and entered. She pushed the door open and walked straight up to the stairs. The house is empty. Amatis is probably still in the party, celebrating the victorious battle between Valentine and the glorious Shadowhunters.

The room Amatis had provided for Clary was large enough for her. The bed was near the corridor towards the bathroom, and small closet. The sheets were neat, unused and soft. Jace thought he just entered Isabelle's room from the Institute, but he did not.

Clary stopped in the middle of the room, waiting for Jace to follow her. He entered the room and walked to her. "Can you stay? I don't want to be alone." She locked her arms around, resting her head into the crook of his neck—finding herself smelling that familiar and amazing scent. He trailed his fingers into her red curls, finding it soft as a feather.

"I'm right here. I won't leave you." He whispered, leaning down to kiss her forehead. She felt his lips on her skin, making her cringe and shiver inside. She never felt happier with anyone like this before, until she met Jace. He had changed her, to be a better version of Clary and that's a good thing though.

Jace lied down next to Clary. He kept her close as possible, their hands twined together like it doesn't want to let go again. Clary was still awake; she kept on wondering about things. Then, he leaned down. "What's wrong?" He asked, again.

She did not answer. Looking up, she found those knee-weakening golden eyes. She pressed her lips; she doesn't want to tell him. "I'm sorry, Jace," she muttered.

She pulled away from him, which made Jace look more worried.

"What are you sorry for, Clary? Please, tell me." He convinced, pulling her arm back. She turned to him, trying to avoid him. Tears had strained her cheeks, ruining the sudden happy face back into a worried and scared look. He instantly jumped out of the bed and ran in front of her. He saw those drops of tears sliding into her cheeks and lifted her face.

She shoved off his hand and stared at him helplessly. "I'm so scared, Jace. What if he come back and found you? What if Sebastian comes back to kill you because you killed him?" Her voice trembled with so much fear, choking her words back into her throat. He placed a finger in her lips and hushed her. He leaned forward, planted a reassuring kiss into her forehead, while his other hand caressing her bare arm. He also was worried about that, because for everyone knows, Sebastian had demon blood in his system and his body isn't found yet.

"He's not gonna hurt me, or you. I promise." Jace promised. But that didn't calm his girlfriend. He looked away and pulled her into a reassuring hug, "If I'll have rip his throat out or cut his head off, I'll do it. I'll never let him hurt anyone, Clary, that's my promise."

Then, Clary smirked with humor. Jace smiled hearing her soft laugh, and wiped the tears away from her cheeks. "Thank you, Jace."

"You don't have to thank me." He stated, "I'm doing this because I love you."

Clary locked her eyes at him, curving a small smile in her lips, "I love you too, Jace, always."

Jace watched Clary, in his arms lying down with her eyes closed.

She fell asleep a few minutes after their conversation. Jace knew what she was feeling. He was scared too. What if Sebastian was alive all along? What if Jace hadn't really killed him before? He looked down at her; she looked exasperated—about all the random things happening around her.

Stumbling to this girl in Pandemonium Club is the best thing that has ever happened in his life. The first time he saw her is the best night of his life. If something happened to the girl he only and will only love, he wouldn't forgive himself, no matter what the consequences are.

Then, the door creaked open which made him look back. He did not let go of Clary's hand. He saw the fatherly Luke standing by the doorframe with his arms crossed into his chest. Jace lifted a finger to hush down and Luke nodded, seems to understand what he meant. Jace looked down at her, brushing the hair from her face so that he would have a good sight of her fair face.

Luke whistled, catching Jace's attention. He stared at Clary and turned back at the young man, lying down next to his soon-to-be-daughter. "Can we talk?" He mouthed. Jace looked down and removed her hand from his own and walked Luke.

He exited, as Luke pulled the door close. Jace stood in front of Luke with his hands buried into his pocket, and he swallowed. "Was she crying?" Jace nodded, which made the older man opposite to him frown, "Don't tell me you two are breaking up. You just got together."

Jace chuckled softly, and rubbed his eyes. He shook his head. Luke waited for a better explanation. The young man bit his lip and sighed, "She's worried." Luke's frown deepened. Jace stared at him, "That Sebastian might come back, that he isn't dead yet. For all we know, he's half-demon." Luke scratched his head and looked away.

They were alone in the corridor. The hallway was dim, and cold enough. Jace crossed his arms around his chest and sighed heavily. "What do you think, Luke?" He asked, sounding so concerned. He isn't just concerned about himself and Clary, but to everyone—in the Shadow world and in the Mundane world, because if Sebastian might be back he would be stronger than before for sure.

"We'll figure something out. We'll find his body to prove he's dead." Luke patted his shoulder, reassuringly.

Jace looked down, feeling the hand on his shoulder.

"Jace?" His name echoed into his ears, which snapped him out. Luke pushed the door open. Jace sneaked his head inside and saw Clary looking at the both of them, half-awake. Jace entered while looking back at the older man and gained a nod from him, whispering "Don't lock the door." Jace chuckled with such humor. Luke closed the door, leaving the two inside.

Jace walked to Clary and she pulled his slender fingers, intertwining it in between her. "You're awake, why are you awake?" Clary rested her head into his chest, closing her eyes slowly.

"You were gone," Clary answered.

"Oh." Jace stated, "Well, Luke wanted to talk to me."

Clary lifted her head and looked at him, her eyebrows meeting its end into a deep frown. Jace shrugged and planted another kiss in her forehead. "About me?" Clary asked, resting her head back into his chest. His other hand, wrapped around her waist, gripped into her curve as he buried his fingers into her raven hair.

"Yes," he whispered. "Sleep, Clary, you will strength tomorrow."

The sunlight beamed into the bedroom, pushing the darkness away from the room.

Jace looked down at Clary, who was still sleeping into his side. Her raven hair scattered into the white pillow, curls messing around. He curved a smile on his lips, brushing her hair behind her ears. He continued to stare down at her.

"Why do you keep staring at me?" Clary mumbled, opening one eye at him. She smiled blissfully at him. He smirked, leaning down to give her a peck in the lips. His hands traveled down in each side of her waist and her arms linked around his neck. Giggling, she rolled with him and straddled herself into his stomach. His hands locked down into her waist, but she pushed his shoulders pinned into the mattress, giggling loudly.

"Are you trying to seduce me?" He smirked, as she leaned down into him. She did not answer; instead she stared at his lips. To her surprise, he rolled on top of her—laying her under him with her legs lying back into the soft mattress and giggling loudly. He placed a finger at her lips to hush her.

He leaned down to kiss her but he stopped. They both stopped, turning their head sideways. Clary's eyes widened when she saw Luke standing by the doorframe. She opened her mouth to say something but nothing came out, and shut it close again. Jace burst out laughing at the priceless face of his beloved girlfriend. She jabbed him on his shoulders as he continued laughing, then turned to Luke. "Luke, we weren't doing anything. We were just…"

He raised a hand to put her to silence. She closed her mouth again, waiting for response. "Don't worry, I won't tell your mother. She'll surely freak out 'bout that. Anyways, the breakfast is ready. Magnus came over to join us for breakfast, complaining that Isabelle is preparing the breakfast back at the Penhallows."

"Now wonder why he came here. The food made by Isabelle is so poisonous, and toxic." Jace felt another jab into his other arm, harder, which made him glare at Clary.

"Isabelle's cooking is fine, for me. She's great, you know." Jace snorted at her, after saying that.

"It's so… I don't know. Tasteless? Even Alec is complaining about it." Jace stated and turned to Luke, "Wait, I heard you mentioned Magnus is here, is that correct?"

"Yes," Luke nodded his head. He took one more glance, "Now get your asses up from the bed and get ready if you still want to spend the last day inAlicante." Then, he exited the room, closing the door.

Clary turned to Jace, as he looked down at her. Then, she smiled—burying her fingers into his curls. "Morning, Jace."

He leaned down to kiss her once again, deeper and more passionate. Her arms veined around his neck, and had her fingers still in his messy hair. She worked her lips around his own and giggling. Then, he pulled away and locked eyes with her. "Morning, babe."
