I appreciate the feedback, and I'm glad you liked the way we expanded the character!
However, if you're referring to the easter egg where you can find a sex toy in Kounosuke's room, it's something we added back during Revisited and was never present in the original. People often mistake additions we made to Revisited as being present in the OG Morenatsu, but I'm pretty certain if you're referring to that scene, it was added by us. The reason it's not in the game anymore is simply that most of the route got rewritten and it didn't really fit in with the new one.
As for his orientation, If i recall correctly (and SPOILERS for the original ahead, of course), Kounosuke in the original game wants to be the "seme" (top) and reluctantly becomes the bottom. I could be wrong as it's been a while since I played, but he only accepts his "bottom" orientation on the day Hiro departs, leaving him a note promising to be the bottom next time.
Hopefully the clarification helps a little bit to understand how Kounosuke is portrayed in Homecoming!
