*This article contains spoilers. tvNTV Series "Love on a Single Bridge" EP4 (viewership rating 5.4%) reveals the past of Ji Won (Jung Yu Mi) and Moon Soo (Lee Si Woo).
When Jiwon worried about his commute, Moonsu laughed and said, "If you like it even though it's hard, then you really like it. I like this school."
"But where did I hear that?" Ji-won asked, trying to recall her memories. "The rooftop, right? Professor Kong knew right away when he saw me, right? So why didn't you tell me?"
Finally, she noticed Moon-soo. When Moon-soo asked, "Is it a memory you don't want to remember?" Ji-won replied, "No, it's not that. I was blind at the time, so I didn't notice anything.
I didn't remember you, Professor Ng," he said apologetically. After graduating from college, Ji-won joined her dream job and took the side of a colleague who was sexually harassed by the CEO, but the colleague changed her story and was fired.
Shortly after, she lost both parents in an accident, and her father's accident caused conditions at home to become strict, leading to a sudden decline in her eyesight and the growth of gray hair.
At the time, Moon-soo, a national swimming star, was hospitalized with injuries serious enough to force him to retire.
Mun-soo, who was hanging from the railing on the hospital roof, saw Ji-won's back hanging from the other railing and said, "Grandma,
Shall I help you?" The two of them talked about how hard it was to do something they loved, and decided to jump off together.
But for some reason someone grabbed him by the neck, which thankfully prevented him from jumping.
