We get to learn a bit more about Ryuutarou's dark past. I don't see why he feels so responsible about it, though. Well, as I wrote before, the story isn't the strong point of this manga anyway.
The second chapter about Mitsuaki opens the door to the love-(insert complex geometrical figure here). I don't find it to be all that realistic. Did I say the story isn't the strong point of this manga?
The art is the real reason I continue to buy these. It's consistently beautiful and easy to follow.
