Beitang Chen, the favored son of heaven, fell in love with his eldest brother's friend Bai Dianqin at a glance when he was 21 years old. Later, he accidentally learned that Bai Dianqin was devoted to his elder brother, so the sinister Beitang Chen secretly hatched a plan to lock Bai Dianqin away. But before the plan could be implemented, he was panicked by a marriage contract. Adhering to the principle of not giving up until he gets Bai Dunqin, Beitangchen ran away from home overnight. In the end, he fainted from hunger and was taken back by Bai Dunqin by accident. Bei Tangchen then resorted to tricks and pretended to have amnesia to stay with Bai Dunqin. Unfortunately, Beitangchen didn't know that Bai Dunqin was the real big bad wolf. So when the big-bellied guy meets the little-bellied guy, a tug-of-war about "love" begins.
