You're making it sound like it's a bad thing, common
SK made a poll on discord about giving Raven a deeper storyline and potential romance path, since a lot of players liked her.
Personally I have mixed feelings. On one hand, I do find Raven the most attractive girl and would be happy if she became a LI. On the other hand, I'd rather SK stick to his own vision, instead of altering his story just because people demanded it. So, we'll see.
Also, I'm really curious about Dora's real agenda and her involvement in the trafficking business. So far, it looks like the most interesting LI storyline to me.
Again, just speculation, but I think Mio/Sylvie will be that throuple where you're either with both of them or with nobody. I like Mio a lot, but I can't stand Sylvie - there's something off-putting about her, no, not because she was bitchy; I just can't put my finger on it.
Anyways, my top-3 girls so far: Raven/Gemma/Dora.
