He got his memories back at the very end tho plus we’re getting side chapters soon
He remembered the only very beginning of metting Pilwon and thought it was Dooshik so yeah i wouldn't say he got his memories back
Nah see chapter 90 or 91 I think the ice cracks and they both fell in the water and kissed each other it is same as when uke saved seme from tide he remembered everything at that time. The scene you are talking about is when uke just wake up and forget everything...
I think this is the closest thing we can get to a happy ending.
Tho I don't like the fact that uke never properly heal from his trauma, it's like he live in a lie never knowing what happened as Dooshik will never tell him, missing such a big part of himself and their story.
But at the same time, I like it. It was too cruel for Jooin to live like that, all the things he had gone through is impossible to recover, even if he tried to he'll need endless medication, therapy and he'll need to live and grow with it.
So I'm saying there can never be the "perfect ending" where they just live happily ever after with all the trauma.
Even if you're not content with the ending if you try putting yourself in their perspective, I think this was best alternative the author could choose
