Thirty Rules for Life as Husband and Wife

Modern-day tsundere rich kid Xiao Junlin got drunk and fell into the sea. When he opened his eyes, his soul had transmigrated to the Great Xia Dynasty, where he had become the heir to the Prince of Zhennan, newly married.

At that moment, in the bridal chamber, his beloved princess consort, Su Chanjing, the Grand Tutor's legitimate daughter and the coldest beauty in the capital, coldly slapped a three-foot-long silk document onto the table: the “Thirty Rules of Marriage.” Every clause was harsh: they would live in separate rooms, keep their distance, avoid bothering each other, and obey her in all things.

Capital rating: laughingstock. Please improve your image as soon as possible. This System will help you become a worthy, doting husband. Friendly reminder: breach penalties come in many forms. Host, please behave yourself.”
