Hrrrmmmm... Rapidly approaching an end? I wouldn't be surprised. This manga seems like it's basically told the story it wants to tell. I can see it getting wrapped up in a couple of chapters. Apologize to plain-girl, she confesses, he turns her down, he starts working with Tirol as a producer or some shit, the end.
Or it's some devious plan. Though I dunno what more the story has i n store though. Would need a new antagonist.
