Scara and you are in the same class. Every semester, y'all fight over each other for parallel 1st place, but y'all don't hate each other.

In this semester both of you decided to study together, he'll teach you physics, and you'll teach him chemistry where y'all are weak in that subject.

During study together, you realize that he is not as pure as you think, and it seems that he has feelings for you. Well, looks like this study won't just be about studying...
