How do you know the hair color of that side character? Or did you mistake that conversation with the MMC? Either way, his hair is probably the same color of Kiyoka or Micchan, if we take in consideration the grayscale here.

This is not how the logic of mangas work, it is always if clothes changed instantly from a panel to the other without the character noticing it.
Since this is more a manga about giving good advices, I think these two could get together, marry, have children and then the guy would be giving good advices about raising a child in the manga long run, honestly I just hope it does not happen just in the last chapter.
I want that other guy to get with the annoying bitch so she stop meddling between these two, then the other guy can also throw her under the buss because I can care less about a bitch being happy.
