according to the raws, I guess the girl is the dad’s ex crush’s real daughter. If i understood well
he's adopted , not his real daughter
oh sheeeeet he must have loved that crush too much urgh, TT
according to the flashback, uncle was 23 when shen fu was 8, so did uncle get her when he was 15?! or are they even real father and daughter?
