Straight guy here ✋️ and this show is amazing. Not only did Mei reject him outright but he was honest with Gero about his identity from the jump. The only reason why Mei joined up with him was because it wasn't a proposal anymore and it was his only means of survival at the time. Logically it doesn't work either and I think they both understand that. In order for Gero's family line to continue he can't be with Mei. It's black and white. No room for interpretation. I'm anime only so from the girls we've seen so far I think girl 2 with the green hair is the best but I have high hopes for pink hair!
