Could this song be any more perfect for these two and their never-ending love story?

‘I’m not dumb,’ Zhao Yunlan says. He puts his right hand around Shen Wei’s bicep, indulges his curiosity, squeezes gently. As he suspected, there’s hard muscle under the rich fabric. Shen Wei hadn’t been damaged by a fall from the roof, hadn’t even been ruffled by Wang Yike’s attack; he’s letting Yunlan touch him now, but he doesn’t have to.
He crowds closer still, keeps his hand lingering on Shen Wei’s arm.
‘I know humans, Prof,’ he says. ‘And you’re not one.’

Adult, angst and smut. Zhao Yunlan knows he shouldn’t be attracted to a suspect. Shen Wei’s secrets give their encounters a bittersweet (yet hot as hell) edge.

“I’m fine,” Shen Wei said. His head drooped, forehead coming to rest on Zhao Yunlan’s shoulder. “Yunlan.” And then, “Zhao Yunlan.”Zhao Yunlan sucked in a breath and stilled. He cupped one hand on the back of Shen Wei’s head and fumbled for his cold fingers with the other. “All right.” He breathed in and out, blinking against his stinging eyes. “All right.”

G, h/c. Zhao Yunlan taking care of Shen Wei for a change. This is just plain lovely and impossibly endearing – especially the way the usually messy Zhao Yunlan makes sure to straighten everything the way his Xiao Wei would.

Gut-wrenching AU in which Shen Wei commits the ultimate sacrifice in order to save Zhao Yunlan. I didn’t need my heart anyway…
Vid: Serial Killer AU, by Node Zero (ENG Sub)
It’s a fucking serial killer AU – and the one that’s dead is me, of course! Absolutely brilliant, the way it’s edited it totally works and gives a whole different spin to their relationship.

Who says candy is bad for you? 
This is so much fun – brilliantly made, with the perfect clips that say it all.
Vid: Bai Yu & Zhu Yilong’s love song for each other
Who writes and sings a song about how much they ship each other? Answer: these two beautiful dorks, and I can’t even. I also love the fact that an official TV channel then went and turned it into a fanvid.
Shen Wei and Zhao Yunlan’s Second Meeting – Chapter 1, by Lord_Black_Cloak – 镇魂 | Guardian (TV) [Archive of Our Own]
Zhao Xinci’s son is a shadowy figure that Shen Wei knows nothing of. The man would be rather young for the position of Special Investigation Department Chief (his Haixing title) and Guardian Lord (his Dixing title), but to be able to receive such rank at a young age would speak highly of the man’s skills and accomplishments. Shen Wei knows only this, and that the man’s name is Zhao Yunlan. The name means little to him.
When I saw the way Zhao Yunlan talked to BCE on the rooftop in episode 1, I also thought they must have met before (although that doesn’t quite mesh with Shen Wei’s strong reaction to seeing him at the window). This is a great exploration of the hypothetical first meeting.
