Is no one else bothered by the fact that they did it in the same room as Riku..?

I always found it weird. As a light sleeper, I'd be pissed off

That's so disgusting and is considered SA. I know of people who heard their parents have sex in the same room they were in as kids and they were always super traumatized, one gets nightmares from it.

Agreed but here riku was asleep and didn't even remember or understood what his parents were doing, and the couples didn't did that much, if the child doesn't remember about it then I don't think it's sa.

Okay, at least that
