Love in the Courtyard: Starting with Engineers

Reincarnated as the unlucky guy with the same name in a courtyard house, Li Yu is bound to an emotion collection system.
Qin Huairu feigns poverty and asks for grain? System notification: Strong jealousy received, +1000!
Sha Zhu is going to stand up for his goddess? He kicks over a lunchbox and sneers: "Does a simp even dare to shout?"
Was Xu Damao secretly plotting something? That very night, the entire hospital witnessed the bizarre sight of him running around half-naked.
Until one day, the system suddenly popped up a red warning: Strong murderous intent detected, the source—a deaf old lady?
Li Yu laughed: Finally, something exciting is coming!
