Canon
The relationship between Futaro and Miku does not start in the best way, since she meets him for the first time and during the first chapters she does not participate in his lessons, remaining distrustful of him. It improves when the two of them have an argument where Futaro shows her and his sisters potential, since then she starts attending Futaro's classes.

Her feelings for him are clear ever since Yotsuba asks her if she loves Futaro. Miku even goes as far as cooking in a contest against Nino despite having no skill at all, when later Futaro tries both dishes saying they are good both good, making Miku happy. During the summer festival two girls ask Futaro and Miku if they are a couple, and Miku is upset for a moment when Futaro says they are just acquaintances.

Before the school trip, in which there will be a dance, Ichika asked Miku to pretend to be her to reject a person, accidentally Miku says that she would go with Futaro.Later in the field trip, Futaro and Miku while hiding from Yotsuba have a conversation that improves their relationship. Furthermore Miku worries about him when he's not feeling well.

Fandom
The ship FuKu has always been the most supported by the fandom, the fans are also characterized by the rivalry with FuNino, being that in the series there is a clear rivalry between Miku and Nino. Another characteristic is the hatred for Ichika after his behavior towards Miku before and during the school trip. The fandom took the end of the work badly, to such an extent that works were born that had the intention of correcting the ending with Miku as the winner. A similar thing happened in the Nino fandom.
