Lin Yuan: I’m a Beta, my biggest wish is to meet a nice Beta girl, get married, have children and live in peace! Wait a minute… Why does my body suddenly feel strange? Why does this medicine look like drugs to prevent Omega from entering estrus?

Trembling in his roommate’s arms Lin Yuan blushes and tries to push off his chest: “Wait…wait a minute…I’ve always thought of you as a friend. Don’t do this…..ah….”
