Plot
Yohan Do spies on Dajeong Lee working at a convinence store from a cafe across it. He mentally notes that there weren't many customers today and that he could see her best from the cafe. Yohan also realizes that it's raining and wonders if Dajeong had an umbrella. Yohan sees her getting sleepy, yawning, getting bothered by an returning annoying customer, get bored and counts something in the ceiling. He starts feeling like a stalker and wonders how to approach her naturally and get closer to Dajeong.

She leaves, telling the manager that she was taking off now. Assuming she doesn't have an umbrella, Yohan attempts to have his chance of approaching her by offering his umbrella until Dajeong opens up her own translucent pink one embedded with flowers, making Yohan decide that today isn't the day. Yohan follows Dajeong, seeing her buy some food and put on makeup from a stand. 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 decides that today's definitely not the day.

While following her as she uses her phone, he contemplates that every time he gets the courage to talk to her as she turns away. Yohan notes that it's cold today because of the rain and the forecast said it'll be sunny tomorrow. He then imagines 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 is about to think that if she would, Dajeong turns around and Yohan hides behind the backside of a car. Dajeong admitted she felt like someone was following her and assumes it was her imagination. The shy Yohan blushes and his heart beats, continuing his thoughts he's not sure what she'll think of him. Wondering if it's okay to get up now, he notices Dajeong is gone. He panics and goes 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 witnesses her getting snatched by men in a limousine that appeared. Knowing he must save Dajeong, Yohan makes a run around the building and stands on the street, allowing himself to get hit by the limousine. The leader asks what was that, and the driver says that he thinks they just hit someone, much to the leader's frustration. Since they didn't have time for this, he orders the driver to get out and check to decide to take the "body" or not. The driver checks on a seemingly unconscious Yohan, who attacks him with a taser. The leader, not watching, wonders what's taking so long, and when the door opened, he thought it was the driver when it was Yohan. After the leader asks who he is, he gets kicked in the face by Yohan, who puts the seatbelt around the leader's neck which surprises the other goons. After a fight inside the limousine that results in a window cracking, Yohan leaves with an unconscious Dajeong while the goons are incapacitated and bloodied. He lays Dajeong against a wall and puts his jacket over her, borrowing her phone to call the police.

A drenched Yohan returns to his apartment where he lives alone and starts writing in his journal. He writes 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.". His apartment is plastered with photos of Dajeong all over the walls and ceiling, and Yohan declares that Dajeong, as always, is safe today.
