I was only able to get endings 2 and 3, do you have hints for how to get the other 2?
1: put more pressure on shiro to finish things
4: spend more time with shiro when you can & don't stress her out too much
good luck (:
;__; i dont mean to be a nuisance but i cant get ending 1 either!!! ive tried like, everything... is there any more hints you can give?
