I would really like if koku's dad got content for himself, even if is just a little bit more, maybe even been able to get intimate with him... Now i'm just imaginating things...
I'm sure we can develop a much grander rapport with Garu in Koku's path.
But... Well, umm... Considering that Garu's significantly older than Koku, scenes of intimacy with the father might be pushing it... Joseph notwithstanding.
