I have to say, despite not liking Miku much, that was the best kiss so far. I feel like it's the most "pure" kiss too... the others felt somewhat sly, like the quint did it in the heat of the moment to make a memory, whereas here it feels like Miku just always wanted to kiss Fuutarou. So Miku ranks up for me. Nino still has my favorite personality type, but Yotsuba and Miku are increasingly sympathetic.
