Three years ago, Katie Wu disappeared on Park Jae-sung and broke his heart. Now, she's back in Seoul with a tell-all memoir.

When pop singer Katie Wu returns to Seoul, her ex-boyfriend rapper Park Jae-sung demands closure. Where did she go? Why did she ghost him? Is he a monster? And why is she back?

Katie knows she has a lot to answer for, except all she wants is to reconnect with her old friends in Jae-sung's band DOYEN, move on with her life, and explore anything other than music-like acting. But when Jae-sung's bandmate Park Dae-jung is cast in a movie with Katie, sparks fly between the two leads. Will Dae-jung pursue Katie even if it could tear their whole band apart?

How will Katie, Jae-sung, and Dae-jung overcome their feelings of guilt and choose forgiveness for themselves and each other?

Glimpse into the world of K-pop, and join Katie as she seeks healing and purpose in the clever and sexy "Weightless," part of the Her Multiverse series.
