Part 2
The Girl and Gyeon-woo's relationship takes a turn for the better; her cruel treatment of Gyeon-woo is her way of showing affection and the two grow closer. After a day of hanging out, he walks her home in the pouring rain and she demands he meet her father, who is a habitual drinker. Her parents do not take to Gyeon-woo and on leaving, he overhears an impassioned argument between the girl and her mother over her relationship with him. He does not hear from her for quite some time and his life without her begins.
One day however, the Girl calls him and tells him to bring her a rose during class (the Girl attends an all-girls college) to commemorate their 100th-day anniversary. He does this, leading to a touching and romantic scene where he arrives in disguise as a food delivery person into a packed auditorium and watches her play the melody of George Winston's variations on Pachelbel's Canon in D on piano onstage. He presents her with the rose and the two hug while the classmates applaud in approval at his romantic gesture. As part of their celebration, they hit the bars and clubs together dressed in high-school uniforms; she gets drunk and as Gyeon-woo carries her on his back, a stranger slips him a condom. Gyeon-woo drops her off inside and is confronted at her house by her parents again; the father interrogates him and forces him to empty his pockets, where he embarrassingly presents the condom. Her father demands that the two break up.
The Girl does not contact him again and Gyeon-woo naturally thinks they have broken up, until one day seemingly out of the blue, she calls Gyeon-woo to meet her for dinner as she is on a blind date. The Girl introduces Gyeon-woo to the date, who thinks Gyeon-woo is a great friend of hers based on how highly she speaks of him. She is unusually soft and gentle as there is clear awkwardness between the two. She excuses herself to the washroom and appears to not be handling the break-up so well. The Girl returns to the table to see Gyeon-woo gone; he left while she was in the bathroom, but not before offering the blind date ten rules to follow to ensure her happiness. All ten are based on experiences they've had with each other:
1. Don't ask her to be feminine
2. Don't let her drink over three glasses
3. At a café, instead of coke or juice order a coffee
4. When she hits you pretend it hurts when it doesn't and vice versa
5. Surprise her with a rose on the 100th-day anniversary
6. Make sure you learn Kendo and Squash, and more.
7. Be prepared to go to prison sometimes
8. If she says she'll kill you, don't take it too harshly.
9. If her feet hurt, exchange shoes with her
10. She likes to write. Encourage her.
While the blind date recites these rules to her, she realizes how well Gyeon-woo understands her and realizes her love for him. She abruptly leaves her date and searches for Gyeon-woo at the subway station.
They cross paths several times, but never run into each other, so she goes into the subway security office to see the security monitors. She sees him standing close to the edge of the platform (just like she was in the beginning). While an employee makes an announcement in the microphone, she yells his name; he hears and they reunite at the office.
Once reunited the two realize they are at a turning point in their relationship, but, for some unknown reason, the Girl decides it is time for them to part. As a gesture to their happy times, the two write letters to each other and bury them in a "time capsule" under a particular tree on a mountain in the countryside. They agree to meet again at the tree after two years to read the letters together. After burying the "time capsule" they go their separate ways for good.
