I mean, this third entry in the anthology was sorta funny, but the author's self insert made it feel like he only made this because he saw that few minute long joke opening and wished it was both real and had him as a part of it.
So fun looking back to all those references! It really makes me remember how far Sosugu and the others have all come in the manga. I hope we can see some developments like this in the main story soon too!
I will say this much for Yukiko: Unlike all these dumbass straight virgin otaku guys who wouldn't recognize emotional intimacy if it bite them in the ass and gave them aftercare, at least she gets Shizuku's character right.
