Nothing Endures But Change (слэш)

After his impromptu (infamous) snowball class, Wei Wuxian acquires several new shadows, all of them eager for more of his brand of help with their lessons. Lan Zhan acquires a bit more competition for his husband's attention, but if it makes Wei Ying happy he can hardly complain. Lan Qiren possibly acquires more ulcers when he finally realizes where the Lan sect's youngest disciples have been sneaking off to for their study period.
