Love Letter Lyrics (MGS)

Novice lyricist Baek Jiseok enters A&R Co. through a recommendation from his college senior and is assigned to compose the lyrics of a new song for renowned singer Cha Doyoon. However, his lyrics are stolen, and he finds himself on the brink of a lawsuit.
The person who extends a helping hand in this situation to the desperate Jiseok is none other than Cha Doyoon?!
"Why are you helping me?"
Will Jiseok be able to pen his lyrics successfully even as he cohabitates with the unfathomable Doyoon?
