A chad usually from Germany who keeps to themselves. Regardless of gender, they're usually 5'5 - 5'7. They are passionate about creative writing and protecting their virginity at all costs, even death. They once had dreams but sold them to the ultra-capitalistic world of taxes. Is either a ladies man or a ladies woman but only have eyes for those who wreak havoc around them and set the world on fire.
Person A: Wow, Sini's still a virgin?
Person B: Yeah, I heard the last person who asked them out got set on fire!
Person A: Damn, I wonder who keeps doing that.
