Beautiful but frustrating
This is what i'm saying! Oml thank you. I get everyone wants their fav to get everything he deserves and more(Uenoyama is also my fav), but they really trying to rush it. It's perfectly fine for Mafuyu to treasure the feelings and memories he shared with Yuki. It doesn't matter. I haven't seen Mafuyu neglect or use Uenoyama as a replacement so things should be fine.
Yes you can still love and move on from painful memories in the past but they key word is move on. Move forward. If mafuyu doesn't consider uenoyama's actual feelings and perhaps insecurities in all of this....realistically they won't be fine.
You share all the parts of life and you with someone you love...and Yuki was a big part of mafuyus. Yes. But I do think these issues and lingering grief need to be effectively addressed before he can move on and I just personally think putting that role on uenoyama is unfair. Because he loves mafuyu so much however he does it and I don't see them communicating about these issues so I do worry what will happen.
You dont have to 'end' your feelings or 'move on' like some of yall are saying. If it was a break up then yeah time to move on, but when someone suddenly dies you dont just cut the string and lifes all peachy again. You and everyone around you spends years picking up the pieces and trying to make sense of what happened, ive experienced it first hand.
I dont think Mafuyu has to ever stop loving Yuki. He loves Uenoyama and has begun moving forwards with his life while treasuring the feelings he still has for Yuki - IMO its really beautiful.
