I'll be honest, not alot of male/male content out there at lease the ones of my tastes and theres no problem with that if others are against it or not bothered by it. As far as what can be improved, its honestly still a bit early to give any feedback, I kinda wanna see where it leads. though the way the girls are submissive towards the MC gives me master/pet/slave vibes and harem vibes definitely coming from your title.
I have enjoyed version 1.1 but the end where I found i missed some things will push me into 1.5 to see if I can do better and where it leads.
your title shows great potential and makes me excited to wait for the next update!
