Not My Brother? Why Are You Crying When I'm in Love?

[Single female protagonist + campus + daily dog food + healing + commotion about what you can't get (no system)] Lin Lu had been Qiu Yishui's dog licker for eighteen years, and he never became a regular until his death. Rebirth on campus. Lin Lu set two goals. First: Don't die as a licking dog! Second: Enjoy life! —— Qiu Yishui didn't know what happened. Lin Lu, who had been silently guarding her and would never leave her, fell in love with another girl overnight. She didn't understand how a man's heart could change so quickly. She cried and ran to ask Lin Lu. Lin Lu's tone was indifferent: "Didn't you say you always treat me as your brother? Why are you crying when I'm in love?"
