Episode 5 - My Bodyguard Husband Is a Hidden King
Gu Bei, heir to the Gu Corporation, goes into hiding on the streets after a romantic setback, only to be intercepted by his sister, Gu Man, in a luxury car. Gu Man demands Gu Bei return to the family, shoulder his responsibilities, and accept an arranged marriage, but he refuses, citing his unwillingness to marry a stranger. To prevent her brother from "starving on the streets," Gu Man conceals his true identity and arranges for him to work as a bodyguard for her best friend, Lin Xixue, the CEO of the Lin Corporation. When Gu Bei enters the CEO's office with Gu Man, Lin Xixue is utterly shocked upon seeing him, dropping her coffee cup, which shatters. It seems there's a hidden past between them.
