I don't see any problems in that? This is a hentai game and Koihime is an eroge, it peaks curiosity as to how they'll handle the harem scenes and it's not like there's anything worth asking about the event itself when most answers can be found in the opening post.
Can't look elsewhere as I'm not at home and the device im using doesnt have google translate, not that the japanese wiki would say anything about the contents of the harem scenes, so it would require digging through galleries, which I'd rather not so on this device. The sites would probably be blocked by the wifi I'm using anyways.
