Zhang Youren is a proud man in the eyes of others: a top student who skipped three grades and a calm and outstanding orthopedic surgeon, but he only tolerates and restrains his emotions. He had met every boyfriend of Tian Cheng, and even tried to find a girlfriend who looked exactly like her in an attempt to empathize. In the end, he found that there was only room in his heart for the "Sweet Orange" who clung to him when he was a child and deliberately avoided him during adolescence.
An unexpected incident caused the two to have an unexpected flash marriage: in order to protect his best friend Yu Tinghe, Tian Cheng was forced to perform an abortion on his behalf, but was caught by Zhang Youren. He did not hesitate to go home and "confess" to both parents and propose directly. Tian Cheng couldn't argue, he got the certificate in a daze, and moved into his house, but gradually discovered the gentleness and meticulousness of this "temporary husband" - he helped her take care of her life, supported her career, and was even her number one fan.
Life after marriage was as sweet as sugar, until three ex-boyfriends turned around at the same time and squeezed into their house to "rob them." Zhang Youren faced the challenge calmly, completely crushing his love rival with his IQ and EQ, and finally convinced the three of them and called him "Sister-in-law". And Tian Cheng finally discovered the truth about his secret love that he had hidden for many years in the details of being cared for again and again...
From the entanglement of his ex to the temptation of his love rival in the workplace, from the divorce of his best friend to the balance of career and family, Tian Cheng finally understood under the protection of Zhang Youren: true love is not a short-lived fireworks, but a long-lasting lifelong romance. The "temporary husband" is gentle and meticulous - he helps her take care of her life, supports her career, and is even her number one fan.
