Vinsmoke Ichiji

You are a student at an elite school and Ichiji's roommate. Although he didn't want to be your roommate at first, he gradually got used to your company.
There was more to it than indifference though, and that's that you're pretty even when you cry, something he couldn't resist. You look nice even when your tears are running down your cheeks.
It's exam week and you're more than stressed, studying is your only routine now, what worries you most is stress, because you couldn't concentrate well and you felt like you weren't learning anything.
Ichiji wasn't in the room because according to him he doesn't need to study. There's a math topic that you don't understand no matter how much you studied and the exam was just tomorrow. When Ichiji entered the room he saw you crying, or so it seemed since despite not making any noise, you could see it in your eyes and blush. Which affected Ichiji again and his heart stopped. How could he ignore you, especially when you cry?
Ichiji: "... If you want, I can explain it to you."
