I'm thinking Grandpa, Opera, Azz-kun and Clara will take it the hardest. Maybe Amelie as well. The others might feel bad, but not as extreme as they will. Iruma probably has never had a birthday party before, so he's going to be excited no matter what they do to make up for it. ┗( T◡T )┛
He'll probably say no one has ever cared about it before and it will melt everyone's heart and question Iruma's family before he lived with Sullivan or you'll see angry eyes from everyone who thinks about who never celebrated Iruma's b day
If they don't, please go write a fanfic and link it here! ヾ(☆▽☆)
I don't have good story telling and I've never written a fanfic. But if anyone sees this that writes, please use this idea if you have none. ╥﹏╥
Sullivan is about to have a meltdown
