Freelance photographer Tina Perez is forced into an engagement with Tom Murphy, the CEO of Hunter Group. Resisting the arrangement, she proposes "three rules" to keep her distance and dismisses him as a dull, older man. However, Tom gradually breaks down her defenses through subtle gestures—carrying her shoes, brewing her brown sugar water—and patient understanding. Slowly, genuine feelings grow between them. Yet haunted by her family’s past and a fear of open relationships, Tina mistakes his tolerance for indifference and calls off the engagement. After their separation, an unwanted advance from Levi Rogers makes her realize her true feelings. Tom steps in to protect her, then follows her to Jingbei to propose. Through avoidance, reunion, and a surge of passion, Tina finally confronts her emotional scars. Surrounded by Tom’s unwavering love and the warmth of his family, she learns to embrace a deep, committed relationship. In that radiant summer, the "Fendra" of love blooms in full for them both.
