You know what, good for you. You might be onto something living alone and living that waifu life.
That would require @Zaide to have sexual/emotional attraction towards a (fictional) being and he's been pretty clear about that. He's still a weeb though.
I don't know if I ever had a waifu. Plenty of pretty nice fictional women in Anime, but I never had a best girl per say. Haven't seen the Anime yet, but Hana Uzaki would seem like the kind of girl I would like as I like girls that can tease back.
