Author Note: Let me know how you like it! Sorry for taking a bit to update, college has me busy!

Their first fight was not expected. It was not like the ones they had in their "fake" relationship. Lara Jean raised her voice, which shocked Peter. Then Peter spoke almost rudely to Lara Jean, which shocked her, Peter never spoke to her like that before. It felt very real and they both did not like it and did not want it to happen again. The most unusual thing was it happened on a normal day, a normally good day.

Earlier That Day:

Lara Jean walked down the hall and smiled at Gabe as she walked by him. He went to wave, but she never saw it because she fell. Confused, she looked around and noticed Gen laugh loudly and watched as she kicked her books. Her eyes narrowed, Gen tripped her, of course.

Gen stepped over her and sneered, "Lara Jean you really need to learn how to walk in those combat boots."

Gabe helped Lara Jean up and handed her the books she dropped, then she turned to speak to Gen, but Peter was walking towards them, he saw everything. "What the hell do you think you're doing? You have no right-"

"No right? Peter I have every right you broke up with me to get with her!" Gen flung her arms at Lara Jean, the fire flared in her eyes.

Peter positioned himself, so Lara Jean was behind him, "Gen don't you even give me that shit! I didn't break up with you, you broke up with me!" there was a crowd that started to form around them, "I wasn't the one who cheated, or did your delusional mind forget that?"

Whack!

Lara Jean's eyes widened, Gen had slapped Peter. She stepped forward in front of Peter and took in a deep breath. "Gen what the hell did you-"

Mr. Sugarman yelled down the hall, "Gen my office, now! Everyone get to class, or you'll be getting detention for a week!"

The crowd broke up and Gen flipped her hair before going to his office. Lara Jean put her hand in Peter's, so she could pull him into an abandon classroom that was not used anymore. She locked the door and sat down across from him. The right side of his face was very red and starting to swell, great. Luckily, she still had her lunchbox, so she took out her ice pack, wrapped it in a towel, and put it on his face.

"Oh. Ohhh, that hurts. That hurts a lot, ow, ow, OW SHIT -"

"I'm very sorry you're in pain but I honestly don't know what other outcome you could have reasonably expected."

Peter frowned at her. "What is that supposed to mean?"

Lara Jean looked at him for a moment, deciding if she wanted to bring this up. "You know, it's not your job to protect me, right?"

"I know. I'm going to protect you anyway though."

Lara Jean sighed and leaned away from him. "Peter if you didn't get involved, then this would've never happened. Gen messes with me to get time with you, I could practically feel the sexual tension between you two. I'm sure the entire school could too."

"Woah no what are you even saying? I was defending you because she tripped you! I'm sorry if you think that was sexual tension but it wasn't. It was me being pissed at her for treating you like that, I didn't trust that you would speak up for yourself!"

They both stood up and stared at each other, Peter moved so they weren't as close anymore. Lara Jean raised her voice at him, "I don't speak up for myself because you don't give me a chance! No one does, you, Margo, and Chris, you guys just want to speak over top of me and involve yourselves in my drama. I don't need you, I don't need anyone!"

"Well," Peter locked his jaw, "I guess you and my dad have something in common."

Lara Jean recoiled back in shock, he never spoke to her that way before. She went to reply but he was already out the door. Well that was not how she was expecting her day to go. A single tear rolled down her face and she wiped it away quickly. Peter didn't have practice today she decided to drive quickly to his house and was surprised when it was empty.

After 30 minutes she needed to start dinner, so she went home and did just that. Her father and Kitty could tell something was going on. They decided to leave her be and dinner was very quiet. Kitty was hoping to see Peter that night but chose to keep her mouth shut about it.

Lara Jean grabbed plates off the table, but her father wouldn't let her clean them, "Honey I got this why don't you go have some free time."

She nodded at him and made her way up to her room, Kitty's concerned eyes followed her. When she opened the door the tears she was trying to hold back trailed down her cheek. Her hand reached to turn on light, so she could see properly but gasped when something, well someone, took a hold of her and so they could pull her close.

She didn't need the light on to know it was Peter.

He opened his mouth, and she assumed he was probably going to apologize but her lips stopped him. At that moment Lara Jean decided she didn't need to talk but wanted to feel him. To make her wants known she lightly pushed him down on the bed, so she could straddle him. Peter had another idea and flipped them over, his lips deepen the kiss as his hands caress her cheek, wiping the tears away. They break apart for a moment and Peter begins to kiss her forehead, nose, cheeks, chin, and then her neck.

Lara Jean gasped loudly when Peter sucks in her skin between his teeth. It felt so good, she was not prepared for that. He does it again, closer to her ear, and she arches up into him. The hands on her back slip under her shirt and pause when they don't feel a bra strap. Peter sucks in another patch of skin as his hands slowly move towards her front.

Her sense were on overload and very, very, loudly she moans, "Oh Peter."

"Lara Jean? Are you ok?" Shit! Her father! Peter jumps up and looks for somewhere to hide.

"Quick the closet!" Peter runs and gets in it just as her father begins to knock on the door. Lara Jean fixes her hair before opening it. "Yeah dad? What's up?"

Dr. Covey looks at her concerned, "Are you ok? You've been acting so weird tonight and then I heard you moan, did you hurt yourself?"

She cringes and then smiles at him, "I'm fine I promise, I just bumped my ankle on the edge of my bed. Sorry for being weird me and Peter had a small fight."

"Well honey turn on your light, so you can actually see," he reached in her room and flipped on the switch, "and well with the Peter thing I'm sure you guys will be fine, just talk to him."

Lara Jean nodded and gave her father a kiss on the cheek before shutting the door. After his footsteps made their way down the stairs she let out a breath, "You can come out now."

Peter came out sheepishly smiling at her before flopping on the bed waiting for her to join him. They laid in their usual cuddle position as he ran his fingers through her hair. The day had taken its toll on the both of them.

Peter very quietly whispered, "I'm sorry. I shouldn't have compared you to my dad that wasn't right of me. Lara Jean, I need you to understand that I don't want Gen. I want you and I love you, I'll work on not fighting all your battles but sometimes I will because I'm your boyfriend."

"I'm sorry too, I've never been in a relationship before so this still all new to me. I do need you though, I think I need you more than I've ever needed anyone in my life. Can we promise to never walk away from each other until we make up?"

Peter sat up and pulled them into a sitting position. "Pinky promise?"

"Yes," she giggled as her heart melted, she was so incredibly lucky to see this side of Peter Kavinsky.

Their pinkies wrapped around each other's and they kissed softly. Peter chuckled as he pulled back and moved her hair from her neck. "So… you might be needing some foundation in unusual spots tomorrow."

"What?" Peter pulled his phone out, snapping a picture of her, she then saw the three different hickeys on her neck. "Oh, great this awesome, I can officially die now!"

"Calm down Covey, I think they're kind of hot. Next time I'll put them in places no one can see except for the two of us…"
