a boy named Sebastian that is very sassy, always wrong, and for some reason hates makeup, he likes to be called "cbass" which is strongly disapproved by an amazing, beautiful, courageous, and a bit aggressive girl named Mercy.

A dude who just wanted to be happy without it being at the expense of others. Ended up alone. Has friends but his love life is, in there own words, “over”. In another life they’d probably become a wacky violent criminal. Also a doomer.
Person 1: Have you spoken to Sebastian recently?
Person 2: yeah
Person 1: what did he say?
Person 2: yeah
Person 2: yeah

Someone who fucks. Sebastians tend to wheel birds like it’s nobody’s business and are known to absolutely delete blue cans.
Todd: “Dude where did all the Busch lights go?”
Blake: “Ask Sebastian. I’m pretty sure I saw him deleting some lattes like 30 minutes ago.”

St. Sebastians is a rather below average institution in Needham MA. St. Sebastians has minuscule academic prowess while still being absolutely terrible at all athletics. Even with this horrific academic and athletic reputation, it's culture can be described with no other word than gay. St Sebastians averages about 65 homosexual interactions per day. Most of these are between middle schoolers and high school seniors (There is no age too young for a Sebs Senior.) In fact, their varsity hockey team often indulges in sexual interactions in the locker room and on the ice. In the ISL, St Sebastians has the highest STD and IUD rates. This of course is due to their favorite activity, gay sex. Most freshmen at St Sebastian wear very short skirts without underwear, to give easy access to upper classmen.

The most caring guy you'll ever meet, he's smart, charming and, kind. He's beautiful inside and especially out. An amazing person overall, anyone is lucky to have him as a friend or especially lover. Never take him for granted or you'll really regret it. Make sure if he's alright because he hides it and always taking care of others instead. He's a literal Angel.
