Everyday at 3 pm is the moment I begin to fall in love with you.

Ching is a girl whose tedious life surrounds her family-owned shop. One day Han shows up and claims to be her high school classmate. Ching's everyday life starts to change because she has fallen for Han. Then one day Han suddenly vanishes. Ching looks up for Han's contact info in the school yearbook. When she meets Han's parents, they reveal that Han passed away years ago. If Han were dead, then who is this person that's been coming to see Ching everyday and who is it that Ching had fallen in love with?
