yess i feel the same too ...i mean the i didnt able to understand mafuyu ( pls forgive me if im wrongh on this) attraction towards Ue tho !
Is he saw Yuki in him? Is he only using Ue as a replacement , since he gives yuki vibes sometimes ? is he still conflicted with his feelings still now and cant let go the past ? or it was simply fall in love again ?
i hate when mafuyu still daydreams abt Yuki , ( even through i k its hard to let go of someone u loved the most died and you are one the left alone ) where he should little bit think to progress in the relationship with Ue .
i hope Ue dont get hurt on this , i cant stand him feeling useless to not being a good enough person for mafuyu !
hope , my opinion goes wrongh since i loveboth of them madly , hope they dont go with the pace as AkiHaru !!!

No you're wrong, Ue's the one who changed Mafuyu and in the first place Mafuyu moved on already he's just feeling guilty about his past because maybe the past will repeat itself. Mafuyu's just having a hard time making decisions because he's feeling guilty about his past.
The things that Ue's doing right now reminds Mafuyu's past where the things that Yuki was so obsessed with music and forgot about Mafuyu and in the end they just fought but then again because of music, Yuki left.
Mafuyu's just wanted to be happy but the past kept hunting him and he's unable to foget them.
Uenoyama and Mafuyu are definitely going to argue, and that’s honestly what they need right now. Ue is holding so much stuff back and is doing so many things right now while trying to keep his relationship with Mafuyu stable. Now that he knows the full story with Yuki and Mafuyu, he’s definitely going to see that what he’s been doing is effecting Mafuyu. Mafuyu feels like the past is repeating itself all over again. They’re definitely going to argue because they’re not good with expressing themselves.
