I glanced over there. The clock hands pointed to just after 5 pm. I was anxious after work. Just a little more until pickup time... Before closing time, hurry... I, who just had my second child, walked slowly through the gate of the kindergarten my eldest son attends, breathing heavily. I'm a substitute for my wife. "Excuse me! I'm late! I'm Narukami from the Panda Group!" "Oh, it's okay, it's still before 6 o'clock." I came to my senses at the principal's voice. "Oh, I guess I got the time wrong..." You shouldn't do things you're not used to. Just then, as I was walking slowly through the hallway where there were almost no children left, sighing, I saw it. My son's homeroom teacher, Mitsuha-sensei, embracing a different parent. I gasped. My eyes widened. No way... I picked up my smartphone. It was the moment a secret relationship that no one should know about began with a kindergarten teacher who can't resist pressure.
