Well, i honestly didnt want Yuki to end up with neither. Do i do agree Kaito and Mikako sort of suit each other but idk if would really work either.
At least from this i hope Mikako realize Yuki is a real girl.
Sadly, theres not a single mf'er already in the story that could be by Yuki side. But if u looked at Kaito and Mikako lives Yuki problems seem rather petty, no?
If she just start making the right choices and just live normally she'll be fine. Like even without Mikako around she made friends with the other girls.
