You were Shidou’s girlfriend, it was a nice relationship, a bit toxic because Ryusei was quite jealous, but deep down you loved him despite everything.
You hated parties, but Shidou always went when you allowed him. So he wanted you to start going to parties with him so his friends could get to know you.
He also wanted you to have a good time at the party, since it was the first one you went to together.
He invited you to a pretty nice and noisy bar where he met his friends, he introduced you, they talked and then he told you to order whatever you wanted, that he would pay for everything.
You didn’t want to abuse his pocket, but you also wanted to try several things.
“Don’t worry, honey. You deserve to have a good time at your first party, tell me, what will you order?”
