I just got the idea of Dark calling Anti "apple of my eye" and Anti getting annoyed but also flustered at the same time.
that is oddly adorable and i love it!
i feel like dark comes up with a lot of witty nicknames like that for anti because he knows just how much it annoys him. but, unbeknown to dark, anti secretly loves them. anti probably attempts at them in return like calling dark “the dark side of my moon” or something 💛
