I actually think Minami walking away was a fair reaction. From his point of view some huge guy is hugging his girlfriend at night while a crowd watches and they even bumped into each other awkwardly before this. Kuroe's not the only one with insecurities here he clearly thought he ruined things last time too. The real villain is that producer dropping Shinji in front of actresses like bait and the actress wrapping her arms around him on set. I just want these two kids to talk for five minutes without someone interrupting. That rooftop scene with Manatsu and Ruri was the emotional core though them telling Kuroe she has the same heart as Harugon regardless of her body made me tear up
