I Picked up a Wolf Pup

Tang Zhou had a crush on Xie Shixin for many years. Driven by his feelings, he defied his family's objections and joined Xie Shixin's company, only to endure countless hardships and mistreatment there. Realizing there was no hope with Xie Shixin, he invented a drug to forget him. After taking the drug, one must find an Alpha to mark him during his special period for it to take effect. Tang Zhou spent a fortune to find a reliable agency and a trustworthy Alpha. But the next day, waking up at home, this supposedly dependable Alpha refused to leave. Well, fine. Tang Zhou really liked this person's pheromones, so he decided to keep him around—useful when needed. Later, one night, Tang Zhou suddenly entered his special period. Half-asleep, he was forcibly marked. Through the haze, he seemed to hear Xie Shixin say: "When will you finally forget about him?" "Can you make room for me here?" "Can you like me too?" —— Xie Shixin left home for a few days due to family matters. On his first day in the new place, a strange person barged into his room. This person mumbled incoherently, cried, and was so annoying. But he smelled so good. Later, after learning the truth, the involved party deeply regretted everything. [Some] private settings included.
