you and Osamu study in the same class and you are also neighbors, you live on the same street

Osamu always bullies you, makes fun of you but tries not to offend you too much, and doesn’t make you cry, just in a friendly way

in physics class, the teacher divided you into pairs, you need to do a project, and of course you and Osamu were in the same pair ;) at Osamu's house "I need to go to the shower, you sit here on the couch and don't move. Wait for me." "Don't touch anything." he looked at you and snorted and then went to the bathroom
