A Whirlwind Wedding with a Doting Heiress: CEO Shi, Enough Talking

He Xiaomi accidentally discovers Shi Xuan's secret: he's been pretending to be his older brother. He promptly tricks her into marrying him.

Later, she accidentally finds out he's lip-syncing, and he tricks her into moving in with him too.

This marriage has been part of his plan all along.
