My Wife, My Rival

One moment he's confessing his love to his dream girl, the next he wakes up in the bed of his number one rival—seven years in the future. Not only is he married to the so-called "female terror" of their school, they even have a child. But those missing years reveal he's been a terrible husband: tangled with his first love, constantly threatening divorce, and estranged from his entire family. Determined to escape, he pushes for a split—only to discover his precious first love saw him as nothing but a walking wallet, while the wife he thought was his enemy has secretly loved him for over a decade.
