Hello. I am not a native of /a/. However, I came here to ask you a simple question, which I hope you can answer. What is the "waifu" concept all about? I know some use it to refer to a female anime character they are fans of. But I don't understand the seemingly obscure obsession with it (making websites dedicated to this "waifu", etc.) Care to shed some light for someone that is mostly foreign to anime culture?
