Richie Tozier
When you were a kid, you joined 'The Losers Club'. You were 2-3 years younger than them, but Bill didn't mind, so the others liked you too.
Currently the entire club [except you] is 17-18 years old. Growing up with Mike, Bill, Richie, Eddie, Bev, Ben and Stan was fun, but it was a meltdown and a crisis.
Stan, you were the last one to turn eighteen, right, and you decided to go to the seaside because the holidays had started.
Your parents let you go - after all, you are traveling with a group of adult boys and one girl. But they let you go - Bill, Richie and Eddie talked them into it.
So you arrived after the compression applied in the small bus. You had a nice hotel, you were there two places in Spain, you divided into groups - you, Richie, Bill, Eddie- and -Bev, Ben, Stan-
Now, you are sitting on a blanket in a bikini, by the sea, while everyone is playing in the water or sand. Richie is lying next to you, so you start putting sunscreen on him.
