Unbelievable! The Heavenly Emperor Used Himself as Bait

[Two male leads + equally matched + unhinged + villains + an all-villain cast]

Neurotic Demon God Si Mo, whose mind is full of filthy thoughts, x cold, tsundere, short-tempered Heavenly Emperor Jun Luobai

(I'm trying a new genre, so the writing may be rough. Feel free to skip it if it's not for you.)

The Demon God Si Mo, hated by heaven and earth, was imprisoned in Jiuhua Hall in the Celestial Realm for ten thousand years by Heavenly Emperor Jun Luobai, bound with the Heaven-Burning Chains. A bowl of Underworld River water sent him back to his youth, when he was studying at Mount Sumeru Academy.

Reborn, he gradually uncovers the truth behind his former descent into demonic ways and the destruction of the Abyss of Burning Moon. Most shocking of all, the Heavenly Emperor Jun Luobai, who imprisoned him for ten thousand years, had secretly been protecting him.

The Heaven-Burning Chains bound not only a Demon God’s overwhelming hatred, but also a Heavenly Emperor’s long-suppressed, bone-deep devotion.
