she looks like also the one around eunbi and dayeon, i may be wrong, bad at names and faces. any of these relationships are good to be honest lol. even eunchae isnt healthy for jinju or dayeon, dayeon should just FO these people to be honest, eunbi having a mom complex and secretly plotting about the hetero marriage is already a flag. reminds me of bittersweet con panna but at least fmc is doing her best to not get into the fixed marriage.
the blondie idk about her yet, but i really despise people who 'tease' you but doesnt know the boundaries of teasing and bullying.
