If you want to know the backstory of xiao yans teacher , watch the origins special season, its 3 episodes condensed like a remake of season 1. It shows xiao yan and yao lao how they met. There are the episodes subtitled in the same channel that youre watching the 3 year agreement (even the intro / outro songs are translated which is great) you chould watch the intro of the first episode as its part of the story. Thanks! ;) cant wait for ur reaction on this special :>
