The Third Charm tells the 12-year love story of how two young people with completely different personalities manage to find each other again. From the tender age of 20 to 27 years old, and then to the mature age of 32, will they find love for the third time? At 20 years old, On Joon Yeong is a nerdy, smart university student who wears plain clothes, and plain glasses, and doesn't obsess over fashion. He plans everything in his day meticulously, grows frustrated easily, overthinks things, and is very sensitive. With the guidance of his friends, he takes part in a blind date where he meets Lee Yeong Jae. Lee Yeong Jae is also 20 years old, doesn't attend university, and instead works as an assistant hairdresser. Lee Yeong Jae has had a difficult life and is an orphan who looks up immensely to her brother, Lee Soo Jae, a barista. She is honest, hardworking, and somewhat daring: the complete opposite of On Joon Yeong. Her dream is to become rich, though she would rather get there with her own perseverance. One day, her friend takes her to a blind date group with university students. At the meeting, she encounters Joon Yeong and goes on a date with him. From there, at 20 years old, their love story begins. (Source: AJ at MyDramaList)
