I Put Her Through Tsinghua, Then She Started Chasing Me

This is the story of a man who, after a breakup, meets a gentle, kittenish young woman several years his junior. The heroine is gentle and serene, while the hero is prickly on the outside but soft at heart. He seems cold, but the moment she gets hurt, he becomes fiercely protective and terrifyingly aggressive. They have an older-man-younger-woman romance. She is a student he supports, but fate brings them together, and they fall in love despite the age gap and prejudice.
