My next big idea:
Slowburn romance isekai yuri where two old childhood friends who haven't seen each other in years get sent to another world and have to work together on their day to day life
One is overly aggressive and energetic and the other is more tired but kinder
Maybe there can be some gaster-like bullshit in there with one character knowing more than they let on and have like strange things going on but everything ends up ok in the end ok
