Park Yoochun is an established songwriter looking for someone to sing his next big hit, XIA is a K-Pop star, trying to break out of the mold.

In which I and my loving rock star husband Byun Baekhyun spends our weekends all alone in our bedroom, listening to each other's heartbeat and sometimes to our favorite songs on the radio and TV but today, I was not having it because all I want right now is to listen to my husband's melodious, heart melting voice sing a love song to me.

Park Chanyeol had never expected to be anything more than a part-time high school teacher and a part-time bartender. He had never expected to join his favourite band as their new drummer. And he had definitely never expected to fall for the lead singer, his idol crush since five years ago, for real.

You're sunny's twin sister who happens to be a rock star ;)  

Baekhyun is an exec at a top record label who is under pressure to scout and sign the Next Big Thing. He meets a free-spirited indie rock guitarist who turns his life upside down, along with his definition of the Next Big Thing. Will the cutthroat music industry bring them together, or tear them apart?
