*Spoilers galore*
This made me legit mad. The athletic dude was not off to a great start with how he just starts visiting Kadokura's room every night to make-out, all the while never providing any explanation or reasoning. Then he keeps on butting into Kadokura's issues, only to basically say "You're such an idiot! Just stop being an idiot!". And he acts like he's the victim when Kadokura gets mad. If you have so much time to get angry about him not noticing your feelings THEN TELL HIM WHAT YOU'RE FEELING. Overall, I probably would've liked it if the athletic dude just didn't exist.
