But Ritsu knew about Yuki tho and he also helped finishing Yuki's song,,he also comforted mafuyu ,,also mafuyu told him about How yuki has a deep troll on his heart and his death deeply affected him,,and Ritsu did understand about his situation,,and mafuyu also sorted out his feelings about Ritsu before dating him,,
But also it was difficult to get over your first love easily,,but they sorted out each other's feelings before officially starting dating!!
And the 'die for me' part,,i would say a lack of Psychological well being of mafuyu,,he is an idiot for asking that,,but he also said it the heat of the moment (also he did not know that Yuki would really will die),
Things Mafuyu did for Uenoyama: He accepted the challenge of singing and overcame his fear of past pain because Uenoyama asked him to. He wrote the lyrics to "Fuyu no Hanashi," channeling his grief to connect with Uenoyama's world. He gave him guitar strings and learned about music to share in Ritsuka's main passion. He sought him out in his classroom and broke through his usual shyness to maintain daily contact. He agreed to formally join the band, doing so primarily to stay by Uenoyama's side. He attended the Syh concert and decided to move forward with music so as not to leave Uenoyama behind. Proof that Mafuyu loves Uenoyama: The direct confession ;-; after the first concert, Mafuyu clearly tells Uenoyama that he likes him. The shift in his "safe place"—the school stairs where he met Uenoyama became his new sanctuary. The desire for physical intimacy—Mafuyu is the one who takes the initiative at key moments, such as their first kiss in the classroom. He shows discomfort when he sees Uenoyama too focused on other people. He decided to pursue music professionally because he realized it was the only way to share a whole life with Uenoyama. Mafuyu clarifies in his thoughts that what he feels for Uenoyama isn't a replacement, but a completely new and different kind of love. In the manga sequel, they have been in an official relationship for years; they live together and are deeply in love. Don't talk shit about Given with such spew baseless hate—xoxo.

I have a serious question!!
