I completely agree. He's definitely not the type to cheat. He'd feel guilty about hugging another person. You can also tell from the look he had on his face when his step-daughter was better at calming his son than him. It's obvious (from an outside perspective) that he's insecure. It shows how much he loves his family but it's also really sad that he can't just enjoy the time he spends with them.
I’m pretty sure the dad is only anxious bc he thinks he’s a bad dad. I mean he was always good with his step daughter bc she was grown and mature he probably thought it was easy and he was good but now his son is born and dad prob thinks his son hates him and that he sucks at taking care of him. He probably doesn’t want be a bad dad and thinks his kids are better off not around him. I doubt he’s cheating bc he’s still all over naoto and lovey dovey
