Denki was with 1-A, sitting next to Serro. He was moving his food around, not eating it and looking upset.
Sero, well. Obviously noticed, normally denki would inhale his food-… uh, meteorically and sometimes literally-
S:”, Hey yo, denki, is something wrong your food?”
"Hm? Oh-no, nothing's wrong with it, I'm just not hungry-"
S:”Heh, denki you literally never say that.
"I-I've said that!! Like-once or twice-"
S:”Mhm, both you had eaten like-, an entire bucket of food. T, T”
"Well-I-that's-"
S:”Denki-, what’s going on? Mina told me you’ve been acting, idk, strange lately?”
"W-NO!"
S:”Yeesh-, calm down! I was just asking!”
