did we read a different manga or what because I literally don't recall mafuyu not being over yuki. In fact he moved on pretty quickly. He literally doesn't use Uenoyama as a replacement and never has, you just made that up. In fact the only person who was hesitant about their relationship IS UENOYAMA. Ue is the one who's hesitant because his bf just told him that his ex killed himself AND Ue is the only one in their band who has any real hesitance with love infecting his music.
Because Ue is really passionate about music, he doesn't want the band to break up and then make it awkward because they dated. He's a real music head and his passion to go professional as a musician where any of the real hesitence comes from. NONE OF THIS COMES FROM MAFUYU NOT MOVING ON FROM YUKI. Because Mafuyu doesn't have these concerns. He does miss Yuki, but he has NEVER EVER implied that he wishes he still dated Yuki. He just misses that his childhood best friend that he used to date is dead now, which is a normal response, because his friend KILLED HIMSELF.

im denying because it literally isn't in the manga. give me a reason, i beg. because if you actually read this manga, mafuyu moves on from yuki pretty fast and it is literally commented by everyone around them. I already don't like uenoyama for his piss poor communication and I already hate people stuck on yuki and mafuyu, so I clearly don't have a bias for who mafuyu likes.
The reality is, Mafuyu literally moved on and there is literally nothing in the manga that implies otherwise unless you give me these damn details

and again if you actually read this damn manga they CLEARLY state why mafuyu and uenoyama are hesitant with their relationship.
Uenoyama doesn't want his love for Mafuyu get in the way of his music career. He loves music so much and when we first meet him he doesn't care for love. He was willing to choose music over love in the beginning. Which is his main hesitation with Mafuyu.
Mafuyu literally tells Ugetsu that he fears that he will have to one day choose between love and music in chapter 48. He doesn't want to choose between either and his BIGGEST fear is that no matter what he chooses, he can't take it back. Especially because he sees Ugetsu do this EXACT fear. Ugetsu had a choice between music or Akihiko. And Ugetsu chose Akihiko. This decision destroyed him, but he kept it and moves on. But Mafuyu is afraid of doing this.
NOTHING about this is about Yuki nor is Mafuyu using him as a replacement. If anything. Mafuyu uses Yuki as a cautionary tale. He never wants music to ruin the relationship he has with Uenoyama, the way music ruined his relationship with Yuki.
Mafuyu pmo so bad like don't get into a relationship if you aren't ready to love them fully. if you can't move on from your past lover, don't use your current partner as a replacement like everytime eunoyama is there he be thinking yuki was there , when he confess to eunoyama does he even think twice or he just straight up confessing to eunoyama and use him just to heal slowly while eunoyama is having a hard time trying to keep it up ( not rlly a hard time but he manage to heal mafuyu )
