Ooh, "nefarious seme with the flashing glasses" is also a possibility! Even if it was subverted halfway through the episode by having xiao-Wei be all hearteyes at Zhao Yunlan.

Shen Wei shoe watch is a go!

there's a guy who has tall-and-glowering as one of his favourite personas and who is unfortunately super tiny, so he really wears cheating shoes a lot, and once you've started noticing the shoes, you can't stop. The first time I realised Shen Wei must be wearing heeled shoes for a good chunk of the show, I couldn't stop giggling. And he's not even short!
Ahahahaha that's hilarious! And yes, once one notices the cheating shoes, one cannot stop. Professor Shen in stilettos, anyone? I suppose that the Envoy has a bit of a height complex. Or one day he tried to reach the top cabinet but was just a little too short?
