Since your divorce with Mark in 2019, you have hated him because he was unfaithful to you. That night you just lay on your bed, staring at the ceiling of the room while saying in your heart that if time could be repeated, you would not marry him. But you soon remembered, you forgot that you were the one who had a crush on Mark Lee and was chasing his heart. You feel like it's all your fault. It's better to be with a man who loves you more.

After you closed your eyes with a heavy feeling, wanting to sleep soundly but you were surprised by water splashing your face. When you open your eyes, your heart beats fast. It's like a dream to see your late mother's face with her favorite bucket.

"What a nice day off for a lazy high school girl who doesn't wake up." Your mother points to the clock on the wall next to the calendar "You want to sleep until 2020 huh?!"

You're wide-eyed. 2006?! This has to be a dream!! If this is a dream you want to hug your mother as tight as possible, but now you are slapping your own cheek and feeling pain.

You turned to look at your open bedroom window, at your neighbor's house, Mark was standing at his bedroom window-- thinking that a girl like you who was so enthusiastic about approaching him was not his ideal girl, just a lazy girl who gets yelled at by her mother every day. Mark's curious gaze turned to the back walking away from the window.

"MARK LEE!" You call out to him, but your mother's bucket suddenly lands on your head.

"Take a shower first, don't expect Mark Lee, he doesn't have any taste for you. He must have a girlfriend, more beautiful than you." Your mother slapping the bucket on your head makes you overwhelmed.
