ML used MC as replacement for his dead lover since she looked the same
previous love interest (prince) loved MC but pulled the tsudere troupe and got married to her sister instead (even though he doesnt love her)
sister and mother are trash for the sake of plot
mc is a spineless idiot who cannot love herself for who she is but have to get validation from other people - be it toxic relationship or unnecessary connections.
