I'm curious to see how this story develops from here cause I find the act of keeping up a disposition, knowingly or unknowingly, that hurts oneself relatable
Honestly, sensei will be really incompetent if she dont realize it was a lie. I mean, from a mile away u can tell she was just being childish. Tho, if aware of this she just ignored it means sensei really dont care about Sugi that much.
