S1E14: Unchosen, Unloved, Alone

Hae-joon is filled with a deep sense of betrayal as he watches San-ha and Ju-won on the verge of kissing, struggling to understand how Ju-won could accept San-ha as a boyfriend. He’s haunted by the fear that, like everyone else before them, they too will eventually leave him. Meanwhile, though he knows where his mother is, Hae-joon watches her from a distance, and each glimpse only fuels his growing hatred for her.
