the incident happened when after class, you were asked by your teacher to bring a bucket of water to water the school yard

you were annoyed and sullen, continuing to grumble along the hallway, but when you walked you didn't pay attention to your steps and tripped, making all the water spill onto someone's body, it was nath who happened to be passing by, with a cold face and stroking his hair nath said

"Little boy, don't cause trouble, what are you doing darling?"
