As enemies close in and betrayal surfaces from within, Grant realizes his latest mission is a lot more personal than he thought.

This episode depicts Gu Bei facing ruthless humiliation from his ex-girlfriend Su Yurou and her mother at the Su family's home. Su Yurou, confident in her postgraduate degree from a prestigious university and her position at Lin's Group, looks down on Gu Bei, who only graduated high school. She demands 1.8 million for a property and nearly 390,000 in betrothal gifts as conditions for marriage, threatening to break up otherwise. Su's mother further mocks Gu Bei, sneering that he'll only be fit for manual labor in the future. Faced with the Su mother and daughter's snobbery and extreme vanity, Gu Bei sees Su Yurou's true colors. He resolutely agrees to the breakup, warns her not to regret it, and then leaves in anger.

In this episode, Gu Bei, the heir to the Gu Corporation, encounters Lin Xixue, the president of the Lin Corporation, at a bar. Lin Xixue is drowning her sorrows due to her family forcing her into marriage. When two thugs harass Lin Xixue, Gu Bei steps in and drives them away with his formidable combat skills. Afterward, Gu Bei takes the drunken Lin Xixue to a hotel. In her inebriated state, Lin Xixue confides her dissatisfaction with the arranged marriage. Impulsively, and grateful for Gu Bei's rescue and his striking appearance, she throws herself at him and proposes to "give herself" to Gu Bei.

Gu Bei (codename "Falcon") wakes up in a hotel room to find three stacks of US dollars and a note reading "compensation" by his bedside. While he's still pondering this, he receives an urgent recall call from his superior (codename "Nightingale"). His superior informs him that Lin Xixue (codename "Qingluan"), the president of Lin Group, is under threat from foreign forces because she possesses experimental data related to the national security project "Stardust." Gu Bei is assigned a three-month protection mission. When Gu Bei receives a photo of his target, he is shocked to discover that the person he needs to protect is someone he knows, Lin Xixue.

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.

Lin Xixue and Gu Bei have an awkward reunion in the office, revealing they had an "accidental" encounter last night. Gu Man (Gu Bei's sister), unaware of this, enthusiastically introduces Gu Bei, who is disguised as an ordinary bodyguard, to Lin Xixue as her personal protector. Although Lin Xixue wants to refuse, she is forced to negotiate with Gu Bei alone under his verbal "threat." To cover up last night's embarrassment, Lin Xixue sets strict "three rules" for Gu Bei and offers him a high salary as "hush money." The mysterious Gu Bei accepts the challenge with a teasing attitude, officially kicking off their bickering dynamic as a couple.

This episode details Gu Bei's bodyguard mission at Lin Group. With his keen senses, he discovered a high concentration of sleeping pills in Lin Xixue's daily coffee. Gu Bei decisively intercepted the poisoned coffee and instructed his assistant, Xiao Wang, to handle it discreetly. He then entered the office to present the lab report to Lin Xixue. Faced with Lin Xixue's doubts, Gu Bei stated his professional stance of "taking payment to avert disaster" and forcefully demanded that Lin Xixue follow his instructions from that moment on to counter the hidden threats.

Lin Xixue, the president of Lin Group, is forced to accept the escort of bodyguard Gu Bei due to safety concerns on her way home from work. Gu Bei successfully breaks through Lin Xixue's psychological defenses by using the name of Lin Xixue's best friend, Gu Man (who is actually his own sister), not only escorting her home but also entering Lin Xixue's private apartment under the guise of a "safety check." During the search, Gu Bei demonstrates a high level of professionalism, but also triggers a fierce conflict by forcibly entering Lin Xixue's bedroom. While shocked by Gu Bei's identity, Lin Xixue is also extremely angry about his invasion of privacy.

Gu Bei discovers a listening device at Lin Xixue's residence through professional investigation, proving that Lin Xixue is under severe surveillance threats. Facing Lin Xixue's strong protectiveness over her private space, Gu Bei forcefully but rationally insists on staying overnight in the guest room as a bodyguard, citing the "drugging incident" and the potential ambush risk. Late at night, Lin Xixue, awake in her bedroom due to unease, tentatively asks Gu Bei through the door if he is still keeping watch in the living room. This episode showcases a subtle shift in their relationship: from initial guarded employment to a growing sense of reliance and warmth.

Late at night, Lin Xixue cautiously tests Gu Bei at her door, worried about her safety. Gu Bei uses sharp wit to tease her about her figure, easing her concerns and solemnly promising to protect her. At 2 AM, Lin Xixue is still engrossed in work, but Gu Bei's attempts to dissuade her are fruitless. Lin Xixue reprimands Gu Bei for overstepping, citing their difference in status and reiterating that he is her bodyguard, not her boyfriend. Gu Bei then霸气 (bàqì - domineeringly/heroically) "princess carries" Lin Xixue back to the bedroom and orders her to sleep in a firm yet ambiguous tone. Their relationship develops a subtle, romantic tension amidst their conflict.
