K-drama fans, mark your calendars — “Dive Into You” dives onto screens on September 26, and the cast just gave fans a reason to be even more excited: their chemistry is apparently too real.
The fantasy-romance drama follows Yoon Ha Na, an A-list actress played by WJSN’s Kim Ji Yeon (Bona), who swaps bodies with her twin brother Yoon Ha Ru (Jang Se Hyuk). Using an old camcorder to time-travel, the siblings race to save Ha Na’s first love, Jung Woo Jae (Park Seo Ham), from a tragic fate.
But offscreen, there’s no time-travel needed — the cast says their bond happened instantly.
