Regarding Woori, heres a spoiler i saw in recent chapters for the curious eyes
from what it looks like its all the way around chapters 35~40 and 46~49 when
they seem to break up :'( and idk like how they kept it going along so long like idk what happens but i see her crying and the chapter title and the images we see as she recalls the events that lead up to it is like right in the kokoro kinda hurt man
so yeah idk like what really happens what kinda events pile up to come to that.
