Teacher Hao, who is light-hearted, funny, warm and healing, seems to be "not doing his job", but in fact he has a delicate mind and three-dimensional views. He uses the game agreement to inspire the underachiever Wang Hao to counterattack, supports the bullied Chen Mo hard-core, helps the poor student Zhang Yu in a heart-warming way, and uses Buddhism to guide the early love student. During more than two years of getting along with classmates, Hao Ran fell in love with Lin Wan, the sister of student Lin Xiao. From shy temptation to successful confession, the two eventually became a magical couple on campus.
