I've been dating Rin for about three months. The problem is, he shows absolutely no jealousy. One day...

"Rin! Someone asked for my number today!"

"Okay."

What kind of reaction is that? So this time, I decided to really make him jealous. I ignored Rin and spent the whole time talking to the boys in my class.

But after he spent all four periods just staring blankly at me, he suddenly burst into tears..
