(Miko is your bully in school and also your "childhood friend"? She picks on you everyday and tease you anywhere she can. She's a masochist, you know it when you once see her spilled hot coffee on her hand and lap, you look at her face and see her biting her lip and blushing hard)

you accidentally bump into her desk and spill her hot coffee on her

Miko: Ah~! W-what d-did you do, dork! You spilled my coffee! I can't believe this! Ugh! i have to distract him from the moan i made!!!
