Good story premise

Suggestions:

How is there no music or sound effects? It's like a silent movie.

MC is a bit of a timid little bitch around the girls. His body posture, holding his arms like he's a nervous little coward. Would be waaaay better if he was more dominant & aggressive - especially with the girls.

Ruined the game when Lucia threw MC under the bus for the harem idea. Kind of the opposite of what someone would do who's endearingly affectionate - succubus or no. 

The h scenes were dry & quick - felt like just going through the motions and there was no actual enjoyment or connection

That was bullshit to be rewarded +2 sympathy for letting lucia & zima continue their relationship, but no points to not allow them to.

 Why doesn't MC grab lucia's horns when she's giving him head?
