He can't resist

Jack starts walking towards her. As soon as he does he regrets it, but he can't stop now. Surely she's seen him in her peripheral and is undoubtedly preparing some annoying and deflecting thing to say.

"So who you texting so early in the morning?" Jack said, trying to be charming.

Kat hits the lock button on her phone and puts it on the top shelf of her locker. She looks up at Jack with those vampire eyes, "nobody," what a fucking surprise.

"Of course," Jack said frustrated as he walked away from her locker and into the cafeteria. He heard Kat giggling in the background like she thought it was all a joke. Maybe she knew it wasn't but she just wanted to avoid being honest. He couldn't tell, and he couldn't help but care.
