Guys, I know you are pissed about Ue never being the center of all, but he is not, he is someone that helps mafuyu finally move on. The story is all about mafuyu, how Yuki was his whole world, and how this world shattered into pieces after his suicide, he blames himself for it and...imagine finding the person you care the most, hanging in the room after you told him those things. Grief is hard itself, it takes a really long time for some people, and if you think that you are the cause of it, it can be harder.
I know that some chapters about ue wouldn't have been so bad, but at the same time it's not what this manga is about, it's about a person finding a way to move on, slowly making his way to feel better
