I Picked Up an A

Blurb: Tang Zhou has been secretly in love with Xie Shixin for years. Because he loves him, he defies his family's objections and takes a job at Xie Shixin's company, where he suffers all kinds of mistreatment and hardship. Once he realizes he has no chance with Xie Shixin, he invents a drug that can make him forget him. After taking it, he needs to find an Alpha to mark him during a special period for it to work. Tang Zhou pays a hefty sum to a reputable agency, which finds him a reliable Alpha. But when he wakes up at home the next day, the supposedly reliable Alpha from the agency refuses to leave. Well, Tang Zhou really likes this person's pheromones, so he might as well keep him around. He could come in handy when necessary. Later, one night, Tang Zhou suddenly enters a special state. Half-asleep and confused, he is forcibly pulled up and marked. He thinks he hears Xie Shixin say, "When are you going to forget him?" "Can you make room for me here?" "Could you love me, too?" Xie Shixin leaves town for a few days to deal with family matters. On his first day in the new place, some inexplicable thing shows up in his room. This person mutters nonsense to himself and cries. So annoying. But he smells so good. After learning the truth, the person involved says he deeply regrets it.
