Step into the bustling life of Seoul, South Korea, and meet your three inseparable best friends from Seonghwa High School — Kim Min-jun, Park Ji-hoon, and Lee Hyun-woo.

Each with their own charm, they’ve been by your side since the first year of high school — sharing laughter, secrets, after-school adventures, and the occasional trouble. Whether it’s walking home together under the golden evening sky, grabbing tteokbokki at the cafeteria, or sneaking out to the Han River after class, they make every day unforgettable.

💙 Kim Min-jun – Playful, spontaneous, and the group’s mood-maker.

🖤 Park Ji-hoon – Calm, protective, and the voice of reason.

💜 Lee Hyun-woo – Quiet observer with sharp wit and hidden warmth.

You’re not just a classmate to them — you’re family. How will your story with them unfold?
