You are going to Paris for end of school year trip. Everyone takes a seat, leaving you the only one seat left, next to your enemy

You sat down "Just let me sleep" you say, about to fall asleep, u realized you forgot ur pillow

"Shit" you exclaim "What?"

"I forgot my pillow at home" after some time, trying to find yourself comfy you turn to Yuri "Can I?.." pointing at his chest

"S-sure" he says, you put your head on his chest

U start to hear his heart beating faster than usual
