Mister Miss www
Sorta..? Or more like I inferred it bc it wasn't quite explicitly stated (but I could be forgetting smth)
He said the reason he became an idol was to find Rokuta and since he didn't find him I figured he may have gotten depressed about it and thought he should try out finding him a different way

After finding Rokuta (and meeting Itsuki) he was actually going to quit fr and have a peaceful happy family incest life but then his savior complex took over and here we are today 😂
