I could've definitely went without the part where he was trying to pull off his piercings, but other than that, the only thing left that I have to say, is the fact that this manga was oddly informative.
Harada never disappoints... Although it was weird and all it wasn't bad AL ALL and imma say it again... I wanna meet Harada and get to know what kind of they are in real life and what came over them to imagine manga like that
