Assassination Classroom
So Karma and Gakushuu are brothers.
Karma is younger, but he skipped a grade so he's still a third year. He's in 3-E.
So one night Karma attempts to sneak out but before he can even touch the doorknob a table lamp flickers on and Gakushuu is sitting there on a comfy armchair and he goes and where are you going? and Karma's like nowhere.
Gakushuu obviously doesn't believe it.
Who would, honestly.
They argue and another table lamp flickers on and Gakuhou is sitting there on another armchair.
They both jump and Gakuhou's like what are you two doing still up and they splutter and asdfghjkl
Gakushuu, like the traitor he is, throws Karma under the bus.
Karma, like the petty person he is, throws Gakushuu under the bus too.
They both get grounded.
Karma just wanted to sneak out and spend time with 3-E.
After that, the idea ends, but eh.
