Lin Chen is a university student who transmigrated into the body of a young man with the same name, the youngest son of Count Lu En. Fifteen years prior, the original Lin Chen was lost and later found, but his true identity was kept secret to protect the family's adopted son, Lu Wuyou. A month ago, after Lu Wuyou framed him for pushing him into water and the Lu family prioritized rescuing the adopted son while letting the biological son nearly drown, Lin Chen severed ties with the family. The transmigration occurred just days before this rupture, leaving Lin Chen with the original owner's memories and a resolve to never return to the Lu household.
Facing poverty in the capital city, Lin Chen struggles to find employment. He discovers he possesses a rare affinity for animals, a talent reminiscent of a druid, which allows him to calm and bond with creatures effortlessly. Learning that wealthy individuals often hire people to walk their companion beasts due to the animals' intense energy and bond with their owners, Lin Chen posts an ad offering his services. Despite skepticism from netizens, he receives a response from Man Di, the assistant to Si Ang, the heir to the wealthiest family in the world. Si Ang’s companion beast, a massive lion named Parker, has been suffering from lethargy and insomnia due to Si Ang's stressful family politics.
Lin Chen meets Si Ang and successfully soothes Parker, revealing his unique ability to connect with companion beasts. Si Ang, initially wary of Lin Chen's motives, hires him to take Parker on a trip to the wilderness to restore the lion's health. Lin Chen accepts the job, unaware that his employer is a central figure in the city's elite circles. During the trip, Lin Chen's natural charm and cooking skills endear him to Si Ang's staff, and Parker becomes unusually attached to him, treating Lin Chen as a playmate rather than just a caretaker.
A travel blogger mistakes Lin Chen for Si Ang due to his resemblance and the presence of Parker, posting an online blog that praises Si Ang's kindness and culinary skills. The post goes viral, significantly improving Si Ang's public image and helping to mend his strained relationship with his grandfather, the head of the Si family. Si Ang, realizing the value of Lin Chen's presence, visits him incognito during the trip. He learns of the misunderstanding and decides to keep Lin Chen close, asking him to teach him cooking and calligraphy.
Meanwhile, the Lu family attempts to force Lin Chen back, believing his severance of ties is merely a tantrum. Lu Zhibai, the eldest son and heir, kicks down Lin Chen's apartment door only to find it empty. Lin Chen has been away on the trip with Si Ang. The Lu family remains unaware of his current whereabouts and his new association with the powerful Si family. Lin Chen continues his journey with Si Ang, navigating the complexities of his new role while maintaining his independence from his biological family. The story follows Lin Chen's transition from a discarded family member to a valued companion of the elite, as he builds a new life based on his unique talents.
