"I'm so jealous of him... he can do everything."
At my school, there's a guy named Nagi Kuon who is popular with both girls and boys.
I like him as a friend. ...But lately, a sense of rivalry has started to sprout within me.
For example, even during club activities_____ The whole place erupts just because he makes a shot.

I've ended up feeling jealous of him.
That's right. I'm always like this. I can't properly acknowledge someone better than me, I get jealous for no reason, and if my love doesn't bear fruit, I cry all by myself... But the person I hate most of all is myself for having this kind of personality.
