Jisoo and Chaeyoung may be exes, but they're far from over.
Ten years after their breakup, they now share custody of their son, Jaewoo. Jisoo works long hours as a waitress, raising him with what she has, while Chaeyoung, the wealthy, sharp-tongued, and annoyingly irresistible, is unfortunately the other parent to their son.
They can't stand each other.
They can't stay away from each other.
And everyone can see they're still in love... except them.
When Chaeyoung steps back into Jaewoo's daily life, old tensions reignite-sharp words, soft moments, and dangerous sparks they both pretend not to feel. As co-parenting blurs into late-night fights and unresolved desire, the thin line between love and hate becomes impossible to ignore.
In the glittering yet isolating world of fame, Jisoo and Rosé's love crumbles under pressure and misunderstandings. After a painful breakup, Rosé escapes to Hawai'i with Jaehyun, sharing glamorous photos that mask her heartbreak. Jisoo, left behind, pours her pain into music while struggling with jealousy and regret.
When their paths cross again in Seoul, buried feelings resurface, forcing them to confront their fears and the love they can't forget. Hawái is a heartfelt story of love, loss, and the fight to reconnect amidst the chaos of fame.
