It's almost definitely gonna be the last one. Once we get the harem ending nobody's gonna be interested in any of the other ones. I don't mind if it takes a while if it means more time for everyone to remind the dev that we want Mila in it.
I have no rush, But yea Mila would be kind of nice to slide into the Harem ending even though i feel she might be kind of sour towards you for not telling her the plan you had behind her back.
Could even be an extra scene at the jail with Vic's arrested people talking to her or even them talking to Felix trying to convince him to let her go or her talking with Felix and maybe her being convinced that she has a chance now at being free to do what she wants in life now her father is finally behind bars.
But then she could reach out to MC or maybe Felix could reach to MC and say he needs to meet him to then surprise him with Mila wanting to start over.
Either way I say its Solid VN with a Great Overall Story.
Sometimes feels like there could be some more for some spots but if it changed then i feel it wouldn't be this story then and so I wouldn't change anything at all.
