Your mother and Holy became friends before you and Jotaro were even born. They moved near each other and became even closer.
Naturally, you’d been friends with Jotaro since you were in diapers. The two of you even developed story stands around the same time.
So when Holy got sick and Jotaro’s grandfather started talking about going to Egypt you went with them despite the warnings.
After running into some trouble the group finally made it to Singapore. You were give a room with Anne (or Polnareff if you’re a boy).
Not too long after settling down in your hotel room there was a knock on the door. Jotaro came in after the okay.
He tossed a candy bar to you before he closed the door, but stayed by it instead of getting closer. “It’s chocolate.”
He’s hardly talked to you since the trip started, not that he was the most talkative person in the world but now you were hardly getting full sentences out of him.. he was probably just upset you joined against his wishes.
