Ch. 6 Shota, borderline pedophile, he could totally get arrested lol. It's pretty cute (ignoring the age gap *ahem*) but I'm constantly on edge cuz HE COULD GET ARRESTED AT ANY MOMENT ISTG. - Dude was drunk one night wallowing in his sorrows and gets picked up by a highschooler and kisses him (totally sexual harassment btw) and they start dating. The vibe is kinda similar to Sayonara Alpha, albeit this is ever so slightly more blasphemous.
Nii-chan (harada)
