My first thought is, if you're having fun and it's free, why not keep going and see how it goes? From what I've heard and the little I've tried, the free to play aspect is pretty good as far as gacha games go. I don't want to oversell it, I don't have first hand experience, but from what I've heard from friends is that it's more than playable.
I think a lot of east Asian games like to write stories where both sides are morally grey, there's a sympathetic villain, or the "good guys" are flawed in some way. A lot of JRPGs do this.
Happy to be here!
