The Waifu FAQ is written in a waaaay too much affirmative way, like, the guy conveys a feeling that he knows what he is talking about however it’s kinda bs
First of all, the word "waifu" comes from the katakana transcription of the English word "wife" so basically, it has to be a girl, just, I precise that if it’s a guy it is called a "husbando" (= husband)
Then, it refers to video game or anime (3D or 2D) characters however I would like to make a larger definition of it by saying that it refers to fictional characters from Japanese related content, so, for example, if the character comes from an American manga, then you can consider it as a waifu/hosbando because manga are from Japan. Otherwise if it’s from a cartoon (like Steven Universe or idk) it is traditionally just called a love interest, maybe now people would include it in the waifu/husbando category :/
Don’t take what I’m gonna say in consideration it’s just my personal point of view, you don’t need to have the Discord Mod starter pack to have a waifu, it’s in the mind so no need to have posters or anything, and it would’ve been better if instead of saying this « you’re not working towards a goal or anything, enjoy her and yourself », he have said something like « make sure to improve yourself so that you give a reason for your waifu to chose you over another guy ». A lot of persons are unhappy in real life even with 1000 waifu/hosbando (I’ll write it w/h to make it short) they are depressed and feel empty : fictional love will, sadly, never replace irl love, you don’t learn how to improve yourself with a w/h because they can’t give you advices and there’s more reason about it but I’m gonna keep it short ^-^
Tbh I don’t really understand what is really confusing you with the waifu concept : you simply feel better with those characters because they convey to you a feeling that makes you feel better or a feeling that you are missing, for example if you tenderness is really missing in your life then you’ll be more interested in sweet and softhearted waifu
