I posted almost the same thing. I shared my thoughts here:
I'm genuinely happy for the two, after his memories came back. But I felt rather empty at the same time : I felt as if the author skipped a crucial period of character development for Ha-Woon, to reconcile the nasty Ha-Woon of the first three chapters, to the Ha-Woon who realized he loves Wan after getting his memories back. When he recovered his memories, shouldn't he have a moment of self-crisis first? I mean, he initially regarded Wan as nothing more then a bug, and now, when he gets his memories back, wouldn't he be in emotional breakdown finding out he is 1)actually capable of falling in love 2) loving someone he disdained earlier and 3)finding out Wan fed little lies to him?
I couldn't help but feel the reason of 'protecting Han from his brother' seems a cop out, and the author could've explored Ha-Woon's character so much more (perhaps a chapter or two) Because as of now, the Ha-Woon in the beginning and now, coupled with his love and finally remembering the circumstances that made him who he was originally, is worlds different and I can't seem to bridge the gap between the two.
That’s definitely a more eloquent way of expressing what I meant so I concur!
Interesting and sweet character development but I almost wonder if he (realistically) would take longer to come to terms with his old persona and new persona instead of just *poof* reverting back to his happy go lucky Wan loving aura. Especially when he has so much fear to overcome regarding his brother and all the years of “training” per se that’s been ingrained into him. Love the happy babies either way!
