Time travel happens every year, and I came to my house today. It's just that as a winner in half of his life, he really doesn't want to start all over again. Now that he has traveled through time and become the third-bedroom young master with the least presence in the house, he still faces a world of husbands. How can he support himself and his widowed father, and try to live a good life? Wait, the young master next door has no intention of being gay!
