Well his reasons are valid and he did express his longing to yoonsung. They both love each other so much they feel like they cant live without one another. Hakyung said that if its not for his brother he wouldnt live on and yoonsung who have hakyung as the only he love and ending up attempting suic1d3 but later on hakyung reminded him to not forget that he also has a lot of people that are dear to him and he shouldn't ignore them for his sake. Because hakyung care for yoonsung so much he doesnt want his cherished people to be gone in his life because of his love toward hakyung yk? I love them so much

I am sorry, but the effort to reconcile being so one sided on Yoonsung's part pissed me off in ways I thought it wasn't possible, lmfao. At some point, Hakyung's wishy-washiness just started to get on my nerves and the fact how much more Yoonsung loved him more than Hakyung loved Yoonsung. The author really should've done a better job at expressing Hakyung's feelings. If you are gonna make the ML a yearner, make the MC a yearner too. One sided yearner stories ain't fun.
There should've have been at least a very brief chasing arc on Hakyung's side to make the wait Yoonsung felt feel more fair like holy FUCK that dude lost so much for Hakyung. The fact he just takes Hakyung back after everything just felt SO anti-climactic, especially how Yoonsung just conveniently gets all his memories back?? Just like that?? Sure Hakyung had his reasons, but there really should've been a point he put more effort into reconciling the relationship than Yoonsung.
