Ji-hae and Soo-kyoung are friends attending the same university and both have a crush on Sang-min who is in their drama club. The more clamorous and outgoing of the two, Soo-kyoung, asks Ji-hae to do her a favor - write a love letter to Sang-min. Ji-hae pours out her own feelings for him on paper, but sadly in her friend's name. Touched by the letter, Sang-min is attracted to Soo-kyoung, and Ji-hae, feeling uncomfortable and even guilty, tries to avoid him. And yet by coincidence or by fate she keeps running into him.
