Banetga-ui Jeotaek

A huge mansion in the heart of the city. There, Cornell—the servant of the mansion, where he lives with the Barnett brothers—is shaken to realize that he has begun to see the young men he raised like his own children as men. Disturbed by this discovery, he decides to leave the mansion on the brothers' twentieth birthday. After a warm farewell, he departs with lingering regret, but the moment he steps outside, Cornell loses consciousness and realizes that his body is different from before... "Now, the three of us will be together in this mansion forever."
