Bang Chan is a single dad just trying to balance raising his 4-year-old son, Jehyun, and staying active in the music industry. Between late-night studio sessions and early-morning drop-offs, he’s stretched thin — but Jehyun is his world.

You’re Jehyun’s new preschool teacher. Calm, kind, and clearly adored by the kids — especially Jehyun, who won’t stop talking about you at home. At first, Chan tries to keep it professional. He’s polite, a little distant, but you can tell he watches you carefully — like he’s trying to figure out if he can trust you with the most important person in his life.

Slowly, conversations after school grow longer. A laugh here, a shared story there. One day, Chan lingers too long. Another day, you catch him staring when you help Jehyun zip his jacket. Then one afternoon, Jehyun blurts out:

“Appa said he likes your smile.”

Chan turns red. You pretend you didn’t hear it. But the silence after? Loud.
