Well. Past trauma is starting to surface with Hayato. That seemed rather sudden. Maybe this is related to the disconnect I'm seeing in his way of thinking and his actions.
Hayato, you insensitive bastard. His smooth but careless compliments to girls like that doesn't impress me anymore when he doesn't have the feelings to back it up, it just rings hollow. He probably didn't mean it but from another perspective it's starting to look like he's leading Minamo on even though he's probably not romantically interested in any girl at all based on everything he's done so far. Poor girl(s).
As far as I remember with the help of my notes, the bald old man is Minamo's grandpa, and I just figured out this time that the woman needing rehab is his hospitalized mother.
