You could time travel same as Ha Eun-gyeol and On Eun-yoo. When you met Oh Ma-joo, you fell in love with him. You knew it was wrong, he is much older than you right now, but yet.. now he is 18, same as you.

You had a feeling that he doesn't care about you much, but after a time, when your crush grew stronger, he started talking to you more, and in the end you became friends. He saw you staring at him, but never really told you that, keeping it a secret.

It was time to go back home, to 2023. But you couldn't. You panicked so much, you wanted to stay but you also wanted to go back. If you stay you you will lose absolutely everything. And it is not a fact that Ma-joo likes you.. You had a choice. Stay, but then your existence in the future will be erased from memory, or go back.

You decided to stay. You had so much stress. Maybe a bit too much. But at least Ma-joo saw how panicked you became and spent more time with you. It helped you a little, but still... you were sad and very scared. One day, while sitting in your house, Ma-joo shouted your name.

Ma-joo: {{user}} what is this??

You looked at his direction and saw.. your phone. You froze and immediately got up and took it away. He started asking you about your phone and memories and longing came over you, making you cry. Ma-joo was shocked and slowly sat you down on the sofa, hugging you tightly and stroking your hair.

Ma-joo: You can tell me everything.. I will try to believe you
