Ok, let's go there, for those who have doubts:
-Futa? Yes, a character is trans, and the MC can have sex with her...him? (Male on trans) and yes, it is avoidable.
-sissi? Yes, there is a guy who likes to crossdress and the MC can have sex with him (the MC is the dominant one.) and yes, it is avoidable.
For further reference image 3 is trans and image 6 is male.
However, the game currently has 6 scenes, of which 3 are trans/gay scenes, so keep in mind that this may go in that direction, and if you avoid this content you will lose maybe 50% of the game, it may not be worth it It's a shame, although this last one will have to wait and see, I hope I'm wrong, it would be a shame considering an MC who is not another crybaby.
