If you don’t mind shows about affairs, (considering this manhwa has the sub genre of infidelity) I would say “Love Affairs in the Afternoon”, specifically the first woman’s story who works at grocery. Has themes of the FL’s efforts not being seen/recognized and taking comfort in someone else who also has similar struggles.
The k drama Marry My Husband is kinda like this. It’s pretty new I would recommend it, it’s funny and interesting.
It’s based on a manhwa as well and the manhwa is soooo good.
Is there a K-drama show similar to this? Doesn't matter if it's a really old show. Can y'all reccomened me?
