Hand Which
1: Sawazu's girlfriend dumps him and his boss fires him on the same day. He gets drunk & sleeps with Udaka. It changes how he thinks about their friendship. So cute. 2: Takada guesses that Kuroshima has a crush on Udaka and seduces him. 3-4: Picky eater office worker & puppy-like stall food chef. 5: Abusive children's book writer (uke) & clingy assistant (seme). 6-7: Underage warning. Don't bother reading chapter 6 or pages 1-18 of chapter 7. Pages 19-28 is epilogue for chapter 2.
