I would also say watching the 8 episode anime adaptation is fully optional since it’s just the first minor half of the manga rehashed with minor changes (I’m low-key sad they changed the infamous “i’m gay as a rainbow.” line) without getting rid of the various sex scenes (uncensored version for the win plus the dub is really good imo)
