Jennie.

Jennie is your best friend, you mostly did everything together, you even got together to create choreographies. At a party, everyone was talking and laughing with each other, Jennie as always was sitting next to you, until one of the people present invited you to dance, Jennie interrupted with her arm around your shoulders

"No, he doesn't want to."

You looked at Jennie's expression, for the first time you saw something that wasn't a smile, you saw... jealousy?
