[Oh, she laughed...but it looked like she caught herself before something terrible might've happened. To Kotarou, her expression sort of looked like...
"I'm on a secret mission. If I end up laughing, it's all over."
Or...
"I have a bomb inside my stomach. Laughing sets the timer. We'll all die. Again." This is quite serious. Kotarou simply points to the teacher that's idly walking by and gives a serious expression of his own. He must be the perpetrator she's trying to catch!
Even if that doesn't exactly add up to whatever Kotarou might've made up.]
