Teacher, I Think I Know You

Opening his eyes slowly, Chen Mu, an overworked office drone from the modern era, found himself transmigrated into the body of Chen Xiaoxiao, a university student. Her advisor turned out to be Song Yuan'an, her ex, with whom she had parted on good terms. As they adjusted to their new circumstances and reunited, they rediscovered what it meant to love, and learned to cherish each other and everything they had in the present.

This novel is set in the real world. The protagonist has no golden finger, only all of Chen Mu's memories from his original identity.
