I like real harems, and I don't care that some people find them trashy.
I like when the MC doesn't have to break hearts, but just tries to keep everyone he loves together by marrying them.
I hate "harems" where generally the best girl never wins, where they introduce 30 love interests and at the end, 29 get their hearts broken.
So I'm fine with this MC marrying Tetra and apparently getting ready to marry Yuria too.
By the way, I love real harems in every genre. I don't really care if the MC is male or female and the sex of his/her love interests, I just like "love fulfilled" stories.
For me, seeing Tetra or Yuria get forcefully married to a stranger would be bad...
