[Crossover] Sorry, I Hate Sports

My dear little cousin is a genius athlete.

My childhood friend is an idiot who can do nothing but play ball.

My invincible junior is the invincible captain of an invincible team.

My dear older brother is an athlete who loves running.

And me, a humanities student who can only play video games, can only tremble in fear among them.

In response to their naive idea, repeated more than once, that I might actually like sports, I just want to say one thing.

"Wake up. I'm just a useless shut-in."

There's no way I'm doing sports. Not in this lifetime.

1. The pairing is set. It's not one of the guys above, but another idiot.

2. The guy pursues the girl. I want to try the love-at-first-sight trope.

3. There are some personal interpretations. The heroine is probably like a combination of Sheldon and Leonard from The Big Bang Theory.

4. A genius nutcase x a hard-working heartthrob

Premise: Happy shut-in life
