This was such an unnecessary ass-pull.

Koga? The senior who was always in the club? Who had a similar backstory to Kinjou? Who was a prodigy? Bitch, when did it all happen?

Stop gaslighting me. This ain't Bleach and author isn't Tsukishima. Stop injecting memories that never happened.

All to create conflict for Teshima like there wasn't a better way to do it. I mean come on man!

Disappointed.
