My Wife Is All Me?

One Soul N Body Su Mu, who had to stay at his parents' home to recuperate due to a broken right leg in a car accident, fell into a large black hole that appeared inexplicably on the floor of his room after playing a game and came to a strange room. Before he could figure out what was going on, with a murmur, a beautiful non-human succubus girl with pink hair, a pair of emerald eyes, and little devil wings and tail appeared in front of him. After the unexpected physical contact, both Su Mu and the beautiful succubus girl showed surprised expressions on their faces, just because they were actually the same person!
