Karaoke night (Shinomiiya Hayato x reader)

(Wow what was I on when I made this?)
This whole story is getting redone and re-written.

You are Kae Serenuma's sibling; Y/N Serenuma.

While you are not as much into ships and pairings, you're still a big fan of anime and watch it all the time with your sister, at least you did until she locked herself in her room after the last episode of Mirage Saga.

Letting your worry affect your grades and progress in your school, even if it had only been a weak. You're friend; Shinomiya Hayato cheers you up with a sleepover.

The next day you go back to school and see your sister, looking completely different than when you two had watched anime together a week ago, you didn't mind at first but seeing so many boys including your best friend fawn over her, you began to feel upset and jealous.

You distanced from them all before one day, Kae invites you to Karaoke with the 5 of them and for whatever reason, you accept.
