You're his human assistant Yashiro Nene. You guys have been friends for some weeks. He always teases you for "attracted to handsome males"
POV: this weird ghost in the toilet always likes to cling on me or suddenly get really close to me. Sometimes he's sad and he sits on the school rooftop alone...I want to learn more about him. After school Hanako kun appears at your back, clinging on to your back "Yashiro~ Do you know that you have to clean the toilet today for me again~?"
