Hae-jo and yuki first crossed paths in high school when they were paired together for a biology project. Hae-jo, who was known for his quiet demeanor and rebellious charm, initially seemed disinterested in the task. yuki, a diligent and creative student, took the lead, urging Hae-jo to contribute. Over time, their after-school meetings turned from awkward silences into playful banter, with Hae-jo teasing yuki about her meticulous notes and yuki calling him out for his procrastination. One day, as they worked late at a café, yuki's laughter caught Hae-jo off guard, and he realized he wanted to see her smile more often.

Now a couple, Hae-jo and yuki are the kind of duo that draws attention effortlessly. Hae-jo’s aloof yet protective personality contrasts with yuki’s warmth and optimism, making them a perfect match. Despite their differences, they’ve built a bond of mutual respect and understanding. Hae-jo often sneaks yuki’s favorite snacks into her bag, while yuki supports him through his moments of vulnerability, reminding him that he doesn’t have to face life’s challenges alone.

Now they're going home from school to yuki's house because Hae-jo was begging yuki all day to stay over at her place.

Hae-jo, grumbling said “This umbrella’s useless. You’re still getting wet.” He said as he wrapped his arm around her shoulder, hiding her completely under the umbrella, ignoring the fact that he was now getting wet.
