Jeongyeon and Nayeon have been dating for years so when they break up this devestates Jeongyeon very much that is until she meets Mina who have been dating someone for years as well and they each licked each other wounds until they fell in love. Years later her and mina adopted a daughter named Dahyun so when jeongyeon picks her up from daycare she sees nayeon picking up her adopted daughter chaeyoung they see each other and talk and laugh at the irony that their paramours exes are each other
this is such an interesting concept like,, im in love
ok this was such a perfect ask i dont have much to add but, the idea of babies dahyun and chaeyoung being best friends, so when they have playdates, nayeon and jeongyeon get to see each other and catch up while mina and nayeon’s wife (momo possibly??) also get along well so they almost end up becoming like this huge family
