Despite me preferring and heavily headcanoning certain ships, I personally do not mind if you don't, or if you prefer a different ship! It's like this: I genuinely don't mind if you ship gumiku or whatever the ship name for gumi and rin is. If you want to ship it, I can't change that.
Honestly, I hope yall aren't the people who will fight people because they don't ship your favourite ship. Its irritating and it can also be why some fandoms have such a reputation. Hell, the vocaloid fandom I'm pretty sure fought over or is still fighting over kaimiku or lenku. I'm not really sure.
This is really random, and makes zero sense why I decided to write this, but genuinely, if you do fight over ships, please, calm down and think about it for a second. If you want to do that, I obviously can't stop you but just think about it before you mess up really badly.
TLDR: I could care less what you ship, stop fighting over ships because it can cause fandoms to have bad reputations and also make people dislike you and the fandom. Calm the hell down and think first kiddos.
