Also, Lee Ji Woon's parents live in a high-end society where most of their friends live with them in the neighborhood and it was annoying for him to meet his aunties and uncles who ask him only one question 'when will you get married'.
So, it was better to stay away from them in his own personal space.
Because of his busy schedule and this attitude of his, his mother made it a rule for him to visit them at least once a week and no excuse from him would be entertained.
He already visited them four days back but today it was his father who asked him to come, just like him his father doesn't do anything unnecessarily without a reason, so he decided to go home as he was sure it is something important his dad intends to discuss.
After finishing his work he reached his parent's home but unexpectedly he ran into Shin Yoon Ah's mother, Song Bing, who was just exiting his house. They felt awkward when they came across each other.
