i'm sure it's obvious to everyone but my number one is heesoul. hmmm this is a hard question to answer about any ship tbh even my favs but...if i had to say something, for now, i'll say how they're both kind of Weird and even though they do tease each other about this, it also feels like they have an understanding and like...solidarity? sometimes. and can match eo when they want to, even when they seem to be in contrast. wait another thing that i want to bring up is that even tho jinsoul is 3 yrs older, she has said that she sees heejin as almost a same aged friend at times; additionally heejin thinks jinsoul is cute in a way that maybe isn't as unnie-ish as other older women around her? so yes i do buy into the cute unnie + mature dongsaeng dynamic alright sue me. but yeah i like that they maybe perceive themselves to be on a similar wavelength even if some things outwardly say otherwise. does any of this make sense. thank you for the question btw!!!
