"Mine, you're mine and I'm yours." Sailub is a stern and cold man who despises Pon, his paper husband. Their marriage, arranged by their families, is nothing more than a formality. Sailub had to leave behind his beloved ex to marry Pon, someone he doesn't love and barely tolerates. In contrast, Pon is sweet, understanding, and endlessly patient with Sailub's cold attitude, though he secretly loves him. Pon's kindness extends to everyone, but his selflessness often leads people to take advantage of him. One day, Sailub receives a call from Pon's friend, informing him that Pon had gone on a "friendly" date with another man and has gone missing. This sudden turn of events forces Sailub, the alpha, to reflect deeply on his feelings for Pon, realizing that his indifference may have masked a deeper, more complicated connection than he ever imagined and went to go find and make everything right.
