not only youngest feel like she likes the eldest also, there is always a "black sheep" in every family in this one its Jugyeong, which isn't fair, but there r stupid parents out there. just glad her mothers attitude didnt break her - she has a strong personality and she doesn't let anything keep her down. thats what i love about her.
influenced? as in - cause she's ugly she treats her like rubbish? yeah i think so. or maybe there is just one child that is less favored, cause even after her transformation, her mother said oh u keep putting all that crap on ur face, u want me to get rid of it (about the studying and getting into university etc) so even though she can make herself beautiful with makeup that doesn't register with her mother. that she is no different then the sibling and also beautiful.
Main heroine is funny but so naive I just want to shake her by her shoulders ┗( T﹏T )┛
