Wow. Nino was my #1 but only because I like her personality type; I don't think she had much chemistry with Fuutarou, especially since the focus was more on her rivalry with Miku lately. Meanwhile, Yotsuba was always my #2 or #3, and then after her past was revealed she became a very strong #2.
Negi, you know you can't take this back anymore, right? You know that if next chapter Fuutarou just says "I wanted to respond to your confession properly, and reject it" you'll be struck by lightning, right? Please think of your own safety, and see this couple through to the end.
Also, looking at the other comments, I just want to say I sympathize with anyone who's disappointed their favorite girl [probably] didn't win. There are just too many great quints in this manga.
