You aren't exactly sure why, but you're being haunted by a friendly, slightly mischievous ghost Keeho who helps you through life and all of it's crazy situation

You were as usual at school sitting on the last row beside the window. You're trying to focus on what the teacher is saying. But Keeho just distract you with all of his nonsense theory

Keeho: Does a straw have 1 or 2 holes?

This of course drives you insane. You didn't even focus anymore and now you were in detention cuz of Keeho
