Quite frankly, Jiang Wanyin couldn't give two shits about what Lan Wangji thinks. "Fine," he says. Shouts. Whatever. He can leave anytime. He hasn't tried yet, but clearly there's nothing for him here. Plus he has a sect at home. Responsibilities. He doesn't run off and goof around whenever he damn well feels like it, unlike some people he could name. "Whenever you decide to get off your ass and go home, you fucking better stop by Lanling."
