Lan Yu is a messy and lazy university student who never bathes and is addicted to games. He hates the world, and the stench on his body helps isolate him from it. When he decides to take an elective course in acting, Lan Yu meets Zhang Xue Yin, a sweet and sunny girl. Motivated by Zhang Xue Yin’s serious and positive attitude - and with the help of his roommates - Lan Yu undergoes a makeover. Will the “new” Lan Yu be able to win over Xue Yin?
