@Im_A_Fandom_Fool yeahh i agree school sucks :( but my advice for headcanons and oneshots are to look for inspiration or wait inspiration to hit ya, maybe try watching an anime to get inspiration to help you write or watching a movie, etc. What I do is I write whenever I feel inspired to or i think of cute random scenarios that might be a good story! (sorry if this sounds bad, I'm not good at giving advice--)
