I Asked You to Come to the Door and Unlock the Door, and You Pried Open the Rich Woman's Heart.

An unexpected order brings locksmith Lin Zhouzhou into the world of Su Wan, a pretty widow from a wealthy family. She thought it was a simple matter of unlocking, but she held his hand and gave him "step-by-step instruction" in the collection room. The atmosphere gradually became ambiguous... Thought it was just a chance encounter, but the aloof female professor Qin Ya fought against all opinions for him and hired him as a guest lecturer in public, with hot eyes. Sister: "Brother, there's something wrong with the way Sister Su looks at you!" Best friend: "Baby, you have met a strong challenger from the academic school!" Lin Zhouzhou, who was surrounded by beautiful women, found that it was easy to open a lock, but difficult to open a happy lock. It was harder to open this fatal Shura field than to open any lock!
