Lu Zhi, known in the industry as the "Cold-Faced King of Hell," was ascetic, aloof, and utterly unsociable. Shen Yu was a notorious spoiled wastrel: brash, sharp-tongued, and irreverent.
They had been at each other's throats since childhood, the fiercest of mortal enemies.
But a family conspiracy forced them to sign a marriage-of-convenience agreement: live together for a year, stay out of each other's business, and each get what they wanted.
Shen Yu thought the marriage worked out perfectly: he wanted freedom, Lu Zhi wanted the right to inherit. A fair trade.
Lu Zhi thought the arrangement was worth it: he needed a reason to get close to the Shen family and investigate an old case from ten years ago.
But on the first day living together, Shen Yu caught a glimpse of Lu Zhi sitting alone late at night; in the first week, Lu Zhi discovered the tenderness beneath Shen Yu's playful teasing; and in the first month, Shen Yu got drunk, leaned against Lu Zhi's shoulder, and murmured, "I feel for you..."
The agreement said, "Falling in love is forbidden."
But no one had told them that living under the same roof as your mortal enemy could throw even your breathing out of rhythm.
As true feelings collided with pretense, and an old case stirred up new hatred,
the marriage that began as a transaction became a trap neither could escape.
