A sunny appearance but a sensitive and fragile writer Shou × A gentle but cold professor Ye Yang doesn't know when he started suffering from insomnia. The long-term reversal of day and night made him very fragile both mentally and physically. The Danmei master who looked cheerful and sunny to outsiders was actually very irritable until the appearance of Xia Yimian, a young professor from the opposite family, and everything seemed to have changed. The tossing and turning nights of the past twenty years or so were probably due to the lack of you, so can you let me sleep peacefully in your arms every night in the future?
