The look gives it all the way. I kinda get him, tbh.
We probably will, if it was as simple as one falling out of love I think we'd know it by now.
Maybe she was the one wanting them but he didn't want to rush it and that put a bridge between them.
Or maybe he's thinking about his dad, judging by what we saw he didn't have a real fatherly presence with Eunsan so maybe he's feeling alienated by seeing a happy family.
oh! this makes sense since like eunsan and his dather have an estranged relationship..
exactly what I thought
the look eunsan gave to that family… he wanted a family? I wonder if we’ll know the backstory of him and his ex wife
