About TQQ

I finished it just now and I kind of understand why people like this (ik my pfp is miku cause I watched season 1 way before just finished the show now)
Although im kinda not sure about the ending, its great but the fact Yotsuba never had that much effect on story in the start but won in the end is crazy cause Itsuki appeard first then Miku falls in love first but Yotsuba was there as a character not as a love interest from the start well its still good though a happy ending is all we need

Who do you think should have won?
(Personally when all characters are this loving a harem ending isn't that bad would have ruined the fun but they were so good of characters to be left out)
