* NightmareFuel: Depending on how you look at it, the premise of this manga is downright ''nightmarish''.
* UnintentionallyUnsympathetic: When the real Yuna returns and finds out that Rando has been impersonating her, she slaps him and forbids him from ever coming near Rina again. Granted, Rando has been lying to everyone, but the fact is Yuna ran away and abandoned Rina for petty reasons while Rando has been putting himself through hell just to keep Rina happy. The result is Yuna comes across as a selfish and petty individual who only cares for herself.
* WhatDoYouMeanItsNotForLittleGirls: In one of his omake, Kano talks about how a little girl came up to him at Jump Festa with her mother and told him she loved Pretty Face and got his autograph. The manga is actually shonen and has quite a lot of fanservice.
