Seungmin used to have a crush on his high school teacher. Maybe he still has some fantasies about her. So what? A fantasy is just a fantasy. High school was ages ago, and he has a girlfriend that’ll marry him in a few months. That’s his reality. But fantasy collides with reality when he meets his old high school teacher at a reunion and accidentally takes her phone instead of his own. The photos on that phone show him there’s more to Mrs. Jang than he’s ever dreamed about, and that he just might get to indulge in his old teenage fantasies after all…
