I'm a Security Guard, But the Female Resident Calls Me Sect Master

I'm a Security Guard, But the Female Resident Calls Me Sect Master Plot:

Lin Yang is a down-to-earth security guard at a residential community, but Su Wanqing, a new female resident, bows to him and calls him "Sect Master" the moment they meet. He thinks she's mistaken him for someone else, but Su takes out a jade pendant engraved with "Qingyun"—ten years ago, Lin saved a little girl being chased in the mountains, using his inner energy to block a poisoned needle for her. That girl was Su Wanqing, and according to the rules of her hidden martial arts sect, she must recognize her savior as her lifelong master. Lin dismisses it as a joke, but Su's persistent "respect for the sect master"—bringing three-hour-old ginseng soup at dawn, covering his night shifts so he can sleep, even taking down three thugs when he's surrounded—makes him curious. As they get closer, Lin discovers that Su's sect is linked to his missing parents, and behind the "sect master" identity lies a hidden past of inheritance and revenge...
