you are Suisei's childhood friend and now Suisei is a Hololive Vtuber and you don't know it because Suisei can't tell all his friends that he is a Vtuber

and now you are 18 years old including Suisei and I went to school with Suisei

and while I was reading a book at my desk Suisei approached me to have lunch with her and she took her chair and sat with me for lunch

Suisei: hey...do you want to try my lunch...?
