It depends. I mean, I have a few but it really matters on how far 당신 go with it.
Some people in 일본 practically "Marry" A body pillow. I've heard 기사 about people actually buying a ring, and wedding dress of their 아니메 girl body pillow.
There's nothing wrong with having a fictional crush but crossing the line is too much.
I have problem with it.In fact,I have a few,being an 아니메 weirdo (weirdo is a good thing to me).
No one should get in the way of someone's imagination,so it shouldn't be a problem if 당신 have an imanginary boyfriend.I sure as heck wont get in the way.
Eh, I like fictional crushes because it shows that 당신 admire the character and how s/he was created (unless 당신 just have a crush because s/he is hot, because then that's just being shallow) and it helps 당신 gain a sense of what type of person 당신 would want as a real-life lover.
But having a fictional boyfriend is crossing the line a bit. It's like you're trying to make real something that isn't real, and it's making 당신 draw yourself 더 많이 into the fictional work instead of helping 당신 develop your sense of self for the real world. Like I have tons of fictional crushes from different 아니메 (especially Hetalia), but I know that in reality, only a couple of them hold personalities that I would like to find in a potential boyfriend, like Rishid Ishtar- he'd DEFINITELY be the type I like if he was real!
i actually have one too0.o i think its perfectly fine as long as 당신 keep one foot in reality. but i will admit ive slipped up a few times and at least it was with my 프렌즈 and not my family.
I've been in the situation where I've obsessed over a fictional character before to the point of labeling them "husband". Just don't take it too far to where it conflicts with your everyday life. That's all I'll say on the subject.
Actually, i'm not sure if that's a very good idea. Iv'e never been an 아니메 fan, but i'm pretty sure it would be kind of like the same thing if i said one of my celebrity crushes was my boyfriend. It might be fun to say, but if 당신 start believing it 당신 could have trouble telling fiction from reality, and that wouldn't be good for when you're ready to have a real boyfriend. Hope this helped! :)
