Qing Ting Wo De Shengyin!!

His old neighbor, Ye Qiaowen, an older girl he had a crush on, just moved back to the neighborhood. But the boy Deng Xianhe knows that she likes someone else, so he keeps his feelings to himself. He is annoyed by how the smart professional woman turns into a useless bum at home, but he can't turn her down when she asks to live with him in a cohabitation arrangement. Along with Xu Yuehan, the capable senpai from his part-time job, and Xu Youzhen, his friendly and outgoing classmate, Deng Xianhe is surrounded by women, each with her own issues. It's the start of a joyous whirlwind romance, with just a trace of melancholy.
