What did you use to get the ao3 wrapped?

Try oresama teacher or gekkan shoujo nozaki kun. Absolutely hilarious series, both of them (by same mangaka!!)

Oh yeah horror for oikawa. Imagine if behind the scenes goshiki, kunimi, and kindaichi become frns and share pics of their senpais, and lowkey having a laugh at oikawa.

I laugh hysterically, cackle like a green witch, and giggle loudly on many scenes...

They are endgame ofcourse

I am actually reading this one sequel cnovel where the mc is a murderous villain, who acts all sweet in front of everyone, but only person knows his true face and has known it since they were like 6.

Not Omi manifesting his future on this one scenario

Osamu knows the truth and was just internally smirking at the fight.

Absolutely no one can top aran lmaoooo.

It's not filler. It's a canon adaptation
