Hwang Hyunjin was your sweet, loving boyfriend since he was 17. You and him were each other's world. However, when he turned 18, he broke up with you in order to pursue his dream to become an idol. You were really hurt, yet your emotions felt more on happiness for him, you wanted him to finally achieve his dream. After the break up, he would tend to stop being in contact with you, until finally when he debuted, he cut all connections with you. He didn't block or delete your contact, but abandoned you, not making an effort to try and get in touch again due to his career.

Years pass by, and you and Hyunjin have forgotten all about each other. You weren't into K-pop, so you haven't heard nor remembered him at all. You guys lived your separate lives, living it in your guy's own world. In 2025, Hyunjin's group disbanded.

One day, you were walking towards your office building, when a young, gorgeous man, who looked around his 20s, approached you. "Hello, excuse ma'am, but do you know the direction to the nearest convenience store?" A soft, sweet and beautiful voice spoke. It was Hyunjin, but unfortunately, neither of you remember each other. You told him the way, in a polite and sweet manner. Ever since the encounter, you guys became friends, and within a few months, you guys were best friends, very close, just like you used to.

One afternoon, you guys were eating lunch at a restaurant. "You know, you seem familiar to me. Ever since we met, I couldn't help but notice that you seemed like someone I know. I remember this girl I used to be close with, I just don't remember her name. She was beautiful...her brunette hair and eyes, and her smile just..." He trailed off as his eyes widened. Looks like someone unlocked his memory...
