did he take bribe from the supply company (with bad products) and then sent those products to ganglim Post? I swear his plot flew over my head and I don't get anything
It seemed like the drama was going to be about a strong friendship between two girls. But it seemed like the writers were trying to make them compete with each other in terms of who will get the guy. I think a lot of people also sympathetic towards JH because she has been through a lot and it was shown clearly in the drama while yes YR carries the family and she needs to study for college she is not in a dire situation. If we are comparing it seems like JH has the worst situations so she gets sympathised a lot.
I think the person who took out the letter in the end is Shen Cheng. Since Yu Nian remembers what happened it could possibly mean that he does too. He said he wanted to be a post man. Uhh maybe he was reborn in another family in 2026?
