Season 1

Wei Qian began to care about a boy he encountered on his way home. When he was following Wei Qian, he named him Wei Zhi Yuan, and they lived together, along with his younger sister Xiao Bao. For survival, he helped the gangsters, but under San Pang's persuasion, he decided to break away from the organization. He decided to duel because Xiao Yuan was kidnapped in anger.

Wei Qian heard the head teacher say that Xiao Yuan was always alone at school, so he recommended Xiao Yuan to participate in club activities. Following his brother's instructions, Xiao Yuan joined the club and almost collapsed. Seeing this, San Pang decided it would be better to have an adult woman at home and prepared to find a partner for Wei Qian. San Pang, Xiao Bao, and Xiao Yuan watched as he met with the girl, but just as they were meeting with a certain woman, Wei Qian suddenly felt unwell.

After graduating from university, Wei Qian joined "HOT," where he faced opposition from the company's CEO, Xiong, while planning an application. To help his brother complete the project, Xiao Yuan suggested his student team to develop it, and they succeeded. The next day, Xiao Yuan returned home to find Wei Qian coughing severely. Seeing Xiao Bao return home safely after the fight, Xiao Yuan took the unconscious Wei Qian to the hospital.

Now, Wei Qian has come of age. He teaches Xiao Yuan boxing, telling him that he needs to become strong enough to protect others. As Wei Qian wraps bandages or instructs him by his side, Xiao Yuan looks at his brother's face with confusion. When Wei Qian returns from a business trip, Xiao Bao confesses that it's strange that Xiao Yuanseems to have fallen in love lately. Wei Qian invites Xiao Yuan to go cycling, fishing, to see how he's doing.

Upon learning that Feng Ning, a candidate for his future brother-in-law, had become a partner in the company, Xiao Yuan became instantly displeased. At the signing ceremony for the cooperation project between HOT and Beautiful Life, Xiao Yuan got drunk and, under the influence of alcohol, confessed his feelings to Wei Qian. From that day on, Wei Qian hardly returned home, so San Pang gave him the money he had saved for studying abroad.
