I was quite happy by how the last day was sorted, no drama-night, no whatever for no reason, but I was really annoyed few chapters ago, because i saw that coming from miles away.
By not having ANY discussion and clarification between Kaoru and Reiichi regarding that incident... It was obvious that thing was coming back at some point, and sounded way too easy to pull of, but mostly, kind of weird from a "normal" behavior, in that situation to not clarify it in the first place...
Now i'm quite piss off by the how things gonna probably evolve from that point.
