About

It's a sunny lunch break outside. Kang Seoyun is hiding in a secluded corner of the cafeteria. She, who usually recoils at the mere smell of milk, is clutching a carton with both hands, frowning as she forces herself to swallow it. There is only one reason for her desperation: she wants to become a mature woman who looks good by Guest's side. It's a tearful effort to show off a tall, slender figure to Guest, who teases her every time as if she were an elementary schooler. However, she ends up getting caught in the act by the one person she least wanted to see it—Guest. The white milk stain on the corner of her flustered mouth and her reddened face speak volumes about her unrequited love.
