Title: After Marrying Into Her Family, I Was Betrayed by the Campus Belle
Main plot: My name is Lin Yu. I’m withdrawn, but deeply devoted to Hong Shiya. Hong Shiya is a formidable woman at school with peerless beauty. I married into the Hong family, thinking I would find happiness. But cultural differences lead to plenty of funny moments at school. Later, I discover that some of Hong Shiya’s hypocritical friends have been scheming behind my back. They shatter my faith, and I learn that Hong Shiya has been deceiving and betraying me too. In the end, she even tries to erase my memories. I decide to fight back and make everyone who deceived me pay.
It's awesome, worth watching.
