There's a silver lining on Sunbae having an amnesia. He's been taking care of his family and more considerate on Hosik that sometimes ended up "neglecting" even his own feelings and self. I can't recall which chapter it is but I remember Hosik telling that he doesn't really know what Sunbae really is "like". So maybe, Sunbae, having an amnesia isn't that bad either, it shows what he really likes and dislikes that Hosik doesn't know about. So let's not be sad everyone ( oh, that's the worst advice ㅋㅋㅋㅋㅋ)
Ps: anyway, I miss the babies. (/TДT)/
What the fuck?! HAHHAHAHAHAA that's it? The ending did not meet my satisfaction. So you'll gonna forgive the person who raped you and ASDLFLFBAHAKSHSGSKSN live happily ever after?
