I'm very stubborn and don't like the kind of storylines with very bad people who destroy other people's relationships, so in this "Guarding a City", there are no women who are as bad as in the Korean drama "The Temptation of Wife". It's just a relationship triggered by a coin. Initially, it was on campus. The encounter, the silent attention, my concern and loss after he graduated, the meeting on the bus after work, the surprise of working in the same company, breathing the air of the same city, walking the same road every day, are all a kind of light and warm happiness to me!
