When a traffic accident leaves her younger sister in a coma with little chance of survival, Shim Bo Nui turns to superstition in her desperation to save her only remaining family member. Two years later, her sister is still unconscious and pronounced to have little time left to live. When a trusted fortuneteller tells her that the only way to help her sister is to spend a night with a man born in the Year of the Tiger, Bo Nui sets out to do just that, no matter the cost. Born in the Year of the Tiger is Je Su Ho, a genius who rose to the top with his inborn skills and hard work and is now the CEO of a top gaming company. Su ho has no interest in dating and wants nothing to do with superstitions. He only believes in science and mathematics; his only love is coding. When these two get entangled with each other, is it already a recipe for disaster, or the start of an improbable romance? And what will the return of a childhood friend and a first love mean for these two? (Source: MDL) ~~ Adapted from the webtoon series.
