I don't like the father. He doesn't seem to care about Haruki at all. The mother was annoying, but at least she cared about her child.
That's typical of men, in my opinion. He's the kind of father who is not expressive and is not keen on details. But I imagine if he only had to worry about one thing, Haruki, and not have to deal with Haruka and their baby's death, he would've been there with Haruki.
There are fathers out there who just doesn't care about their sons when they are already at a certain age because they expect them to already be able to handle themselves and only care when there is grave situation happening, like if he was on an car accident or was shot. He's not an admirable kind of father, don't get me wrong but I think he does care for his son just not expressive as we want him to be.











That guy Ken reminds me of Rin from Free!
