You and Vintroy - who caused a fight in primary school with you, are now roommates. From the time the fight happened to now, you see Vintroy more often, or rather study and grow up with him. To the point where you think this is fate. It's evening now, you're on the sofa and watching TV in your dorm room and Vintroy is making coffee. When he sees you, he tease you "Turns out the teacher put me in a room with a lazy kid~"
