Yohan Do

Hyeseong Choi is the son of Yun Choi and Miyeon So who was held captive for ten years, brainwashed to believe his name was Yohan Do and protect Dajeong Lee at all costs.

Regular Tailing
Yohan found the convenience store that Dajeong Lee worked at. Although he regularly visited the store to watch her in person with his hood up, he found a cafe across where he could see her from, considering it the be the place where he could see her best from other than the convenience store.

Fight against a Criminal Gang
One day, he was watching her from the cafe, realizing that there weren't many customers throughout the day. Yohan also noticed it was raining and wondered if she had an umbrella. Yohan saw Dajeong getting sleepy, yawning, getting bothered by a returning annoying customer, got bored and counted something in the ceiling. He started feeling like a stalker and wondered how to approach her naturally and get closer to Dajeong.

Dajeong left, and assuming she didn't have an umbrella, Yohan attempted to have his chance of approaching her by offering his umbrella until Dajeong opened up her own translucent pink one embedded with flowers, making Yohan decide that today wasn't the day to approach her. Yohan followed Dajeong, seeing her buy some food and put on makeup from a cosmetic store. He briefly lost her until she bumped into him, apologizing while he was overcome with shyness, blushing, running away and saying he was more sorry. Yohan decided that today was definitely not the day.

While following her as she uses her phone, he contemplated that every time he got the courage to talk to her as she turned away. Yohan noted that it was cold today because of the rain and the forecast said it would be sunny tomorrow. He then imagined if it was just the two of them in the world, where they are laying together in a bubble in space, would Dajeong look at him then. As he was about to think that if she would, Dajeong turned around and Yohan hid behind the backside of a car. The shy Yohan blushed and his heart beated, continuing his thoughts he was not sure what she would think of him. Wondering if it was okay to get up now, he noticed Dajeong is gone. He panicked and went around the corner, looking for her and asking himself what was up with today.

With a sense of relief after finding her in an alley, he witnessed her getting snatched by men in a limousine that appeared. Knowing he must save Dajeong, Yohan made a run around the building and stood on the street, allowing himself to get hit by the limousine. The driver checked on a seemingly unconscious Yohan, who attacked him with a tazer. Yohan opened the car door and after the leader asked who he was, he got kicked in the face by Yohan, who put the seatbelt around the leader's neck which surprised the other goons. After a fight inside the limousine that resulted in a window cracking, Yohan left with an unconscious Dajeong while the goons were incapacitated and bloodied. He layed Dajeong against a wall and put his jacket over her, borrowing her phone to call the police. Paramedics also came and it took a minute afterwards for Dajeong to wake up.

A drenched Yohan returns to his apartment started writing in his journal. He wrote down the exact events of the evening in full detail, such as writing "At 6:21:43 P.M.... ...she was kidnapped", "At 6:22:21 P.M., I jumped into the car." At 6:23:25 P.M., I knocked one of the men out.", "At 6:23:50 P.M., I entered the car.", "At 6:27:52 P.M., I took her out.", "At 6:40:40 P.M., the police arrived.", "At 6:41:02 P.M., paramedics arrived.", and "At 6:42:51 P.M.... ...she woke up.". Yohan declared that Dajeong, as always, was safe today.

Personality
As a child, Hyeseong was a socially inept and cowardly boy. This lead to intense loneliness, making his brother his only real friend. He worked desperately hard for his parents approval, as he would study for very long periods.

Due to 10 years of brainwashing, he became intensely devoted to protecting and loving Dajeong Lee. He seems to not understand that he is stalking her, due to his lack of social skills. He is shown to have absolutely no mercy for anybody who insults or harms Dajeong, going as far as publically humiliating them or brutally beating them.

He is also shown to be very smart and skilled in many areas.
