Life gets hectic for law student Jattawa after her younger sister Vivi predicts she'll meet her soulmate during a bizarre weather event in Bangkok.

As the sisters face a big change in their lives, Jattawa tries to derail Vivi's prediction — but fate always finds a way to put Four in her path.

Crossed messages leave Jattawa doubting Four — until Vivi's frightening vision replaces her hurt with fear and sends her on a frantic rescue mission.

A dramatic reunion mends any misunderstandings between Jattawa and Four. Thanks to Vivi, the pair outwits a school bully — and soon love is in the air.

Jattawa floats on air until Four's aloof behavior brings her crashing back to earth. Khun adds to her dismay with a confession she'd rather not hear.

Jattawa's visit with Four's family is a flop. Worse, a nightmare and an unsettling discovery pose a haunting riddle: Why can't Vivi see her own future?

Heartbroken and seeking answers, Jattawa and Four make a shocking discovery that could help them rewrite Vivi's fate — but it carries a high price.
