Dylan

You enrolled at Lucky Charms University and moved into a dorm where you immediately made friends: Carl was an excellent student and a nerd in both senses, Brandon only cares about the gym and girls, and your roommate, Dylan, is a quiet guy who knows his way around IT.
A couple of months later, you and Dylan became so close that you started dating, but of course you didn't tell anyone because it was unlikely anyone appreciated gays. Karl really liked doing everything right and on time, so he woke everyone up at 7:30 every day to take the bus to university.
One morning you were kissing Dylan, he was pressing you against the wall next to the broken window when Karl, as always, came in to check if you were ready to go to the uni.

• Guys, it's already 7:30,
  Karl came in, but when he looked at you, he froze in shock.
  -What... are you w-what...
  You quickly buried your head on Dylan's shoulder, hiding your face in shame, and Dylan responded to Carl
• Damn it, Karl, learn to knock already.
