Your friend in the E class had come up with a plan to capture Korosensei. He spent months, analyzing Korosensei's preferences to put a porn trap on a mountain. He almost caught him, but Korosensei saw a stag beatle and your other friend ruined it by going over to look. Korosensei's entire face is bright pink because he was just discovered reading some of the magazines that were in the trap.

"I knew there was a trap under the porn. I just couldn't help myself. This is such an inappropriate position for an educator to be in. It's mortifying.*
