I Thot You Was a Toad's manga / #drunken sex(2)

Hot shot cupcake yakuza waka #4, Tatsuyuki, is unwillingly sent to Fukouko to assume his duties, gets dead drunk in the midst of a set-up by subversive henchman, Rogi, is rescued by a playschool teacher, Minori, with whom he unknowingly shares a secret from the past. Eventually all these chaotic and seemingly random incidents join together in a surprisingly suspenseful and interesting plot. The villain is definitely a Boo!Hiss!Bad guy, but he has his own treacherous secrets and nothing in this strange little tale is what it seems at first glance. I certainly misread it. Now, I'm all "Read it! Read it! Read it!"

A straight salaryman gets drunk and picks up a bartender passed out on a park bench. Wild sex appears to have ensued, not that he remembers any of it. It's the continuation next morning, in somewhat public spaces, which leaves him hot and bothered.
