"Lila? Lila Rossi? Adrien dated her?" Alya asked, sitting at their lunch table.

"I guess." Marinette sat in front of her.

"Didn't she move back to Italy after that incident with Ladybug? That was sophomore year." Alya stated.

"She did but she ... she came back last summer. I don't know for what." Marinette sighed.

"Just ask him about it. Marin could be bullshitting you." Alya stabbed her salad.

"What is Marin bullshitting?" Adrien asked, appearing next to their table.

Marinette looked up at him, biting her lip.

"Agreste!" Nino shouted from across the cafeteria.

Adrien turned to look at him and nodded when Nino began waving at him, "That's my que."

"Wait, Adrien. We need to talk after school." Marinette fidgeted with the sleeve of her jacket.

"Yeah, okay. See you later, babe." He winked, walking away.

Marinette's eyes widened slightly and a light blush dusted her cheeks.

"Aw, how cute. You two are gonna be so cute," Alya smiled.

"You wanted to talk?" Adrien smiled as Marinette approached her car.

"Yeah," She unlocked her car and got in.

Adrien followed suit and got in on the passenger side, "What's up, babe?"

"I ... I ..." She tapped the steering wheel lightly.

"Is something wrong, buginette?" Adrien frowned.

"Lila." Marinette blurted.

"Lila? What about her?" Adrien furrowed his brows.

"What happened between you two?" She turned to face him, her voice shaking slightly.

"Uh, we dated for a few weeks last summer. It was pretty mellow. Why?" He bit his lip.

"Marin said something about her and you." Marinette answered.

"You listened to Marin? The dude hates me now. He'd say anything to make me look bad. Don't you trust me?" Adrien scoffed.

"He's my brother, Adrien. He just wants to protect me." Marinette retorted.

"Protect you from what? If you don't trust me, how the fuck are we gonna make this work?" Adrien seethed.

"I didn't say I didn't trust you!"

"It feels like you don't!"

"I trust you with my life everyday!"

"No, you trust Chat Noir. Not me. You don't trust me, Marinette. Just tell the truth!"

"Fine! I don't trust you. You sleep with everyone and break hearts and you don't seem to care. So how the fuck do I know that Marin isn't right? How do I know for sure you aren't just after sex?" 

"I can't believe this. I thought we were getting somewhere. But I guess if we're being all fucking honest. I was after sex, Marinette. You would be a good lay."

Marinette gasped, her eyes wide and glistening with tears. Her hand raised and she made contact with Adrien's cheek. A red handprint was visible.

"Get the fuck out of my car! You fucking prick! Get out!" She yelled.

"Mari, I – " Adrien stuttered, unable to find words.

"Get out, you fucking asshole! I never want to fucking see your face again! Get the fuck out!" She screamed, tears running down her cheeks.
