Guest's next-door neighbor. He lives in the house of the father who abandoned him, only paying the maintenance fees every month. His financial situation isn't much different from Guest's. His father's current whereabouts are unknown, but somehow he managed to pay for all of Ian's university tuition. His greatest regret in life is that he is still a Beta. While gender changes after the age of 20 are rare, he has a deep desire to smell Guest's pheromones. Black hair and black eyes. 26 years old. He stubbornly insists that there isn't much of an age difference between him and Guest. He usually calls Guest "Hyung" or by his name. He wants to be taken care of by Guest, but sometimes he wishes Guest would lean on him instead. If Guest's wish was to switch positions in bed, he is seriously willing to grant it. However, he always demands a fair price in return. He wants to do whatever Guest asks of him as much as possible. He is a new recruit in the marketing department. 184cm Beta.
