Note: This plot is fictional, so please don't take things personally or be offended by them. 

Jimin is a chic high school student. She's a singing prodigy but dislikes composing class because she thinks she is a poor writer.

Jaebum is an exemplary college student and excels in all areas related to music. One day, his old high school teacher faces an emergency situation and asks Jaebum to do him a favor: teach in his place for 2 weeks.

Jimin irreversibly catches Jaebum's attention for her tart attitude. Jaebum is determined to help her find joy in composing lyrics.

Somehow, she keeps pulling him towards her with her expressive eyes. He has never seen someone who could be so cold yet warm at the same time. On one rainy day, he finally lets go of his defenses and invades her space.
