I was thrown off by the high schooler until they revealed those are his great grandparents so it's like 100y ago. I know this is kind of a spoiler but it might help people not feel as grossed out by this subplot!
Unfortunately it don't think so, when we asked Shin if the volumes were gonna be translate in english she said that it wasn't planed, the work is probably not famous enough for that
That was too harsh but let's not forget that Woowon keeps trying to resolve things by himself and shutting Seo An out. It may be out of pocket to lash out but it's not surprising Seo An would react that way
Why is everyone giving gyeongchan a free pass even though he constantly breaches mc's boundaries??
Same. Redhead is sweet but has absolutely no respect for boundaries. He's kinda similar to psycho ex boyfriend.
