I think Shen Wei should've just called in and also acquired a larger support network. Currently, it's just him, and he's in full Protect Yunlan mode so he's not consulting Yunlan, and I really think he could do with having someone to share his burdens with, academic, interpersonal, and Envoy-official.

It's really quite telling that he's willing to. But at that point it's really important to Zhao Yunlan keeping this ginormous deal a Really Okay and Handle-able Deal, so Shen Wei cancelling class would be NU-UH. (And, not to open this can of worms, but just now it's also striking me that this is an interesting question that slightly changes colour if you assume they're an official couple vs. if you assume they're not...)

Really, thank you for the cane info, I never noticed and that is DELIGHTFUL. (Oh god Ye Zun, you colossal... something.)
