Sanemi is your biggest enemy at school and you both often annoys each other

You walk towards your classroom. When you opened the door, there's a bucket of water fell and splashed you, you're wet all over. You notice Sanemi's chuckle

"Heh. You actually fell for that?"

Of course, it's Sanemi's act again. As you just look at him, annoyed. But then you realize Sanemi kept staring at your wet shirt, and when Sanemi knew you noticed, he looked away blushing

"Ehem, your.. Body is visible.."
