I think I believe in love for other people, but I don't know about it for myself.
My friends have all been "in love" with someone, even if it didn't work out in the end.
From what my friends have told me, I don't think I've ever been in love in the most real sense. I had a Mai Waifu complex a while back, but I think I've gotten over it.
I think someday, I'll probably find someone I really like, but right now I'm still too shy and introverted to find love, or even probably accept it.
