Papa to Watashi to Ayumu-chan

Even if it's not fate, I want to be with you. Ayumu is a worker at a real estate agent and he's currently worrying about his lack of pheromones and its effect on others. Suddenly, one day, he encountered a super beautiful alpha called Ren who works in the red light district. When Ayumu learns that Ren is living dangerously on the streets with his cute daughter Rui, he decides to help them. When Ayumu sees Ren at his work he starts to fall for him. The slightly unreliable Ren shows Ayumu his more sexual side and Ayumu grows more attracted. However from that moment, Ayumu's pheromone production started to increase and without him knowing he started to seduce Ren?! (Source: Frontier Works, translated)
