>>15376133As someone who was legitimately in a relationship with an anime waifu before, having a 0% chance is by far the better deal. When it's impossible, you're forced to swallow the truth and surpass it. You have no delusion or opportunity for delusion, just the strength of your love despite that it wil never and never come true.
With any possibility, any percentage above 0%, no matter if it's 0.0000000001%, it haunts you. If you fail, you will forever be burdened by the knowledge you could have. You could have. It wasn't impossible. If you were more skilled, more talented, more dedicated, more lucky, it was possible - no matter how unlikely. That small percent chance is maddening. You have to dedicate yourself to it because you can't give up. You have to try for something, that in the end you will lose, will all be for naught, but when you lose you still only have yourself to blame because it wasn't impossible. 0% is infinitely better than 0.00000001%. You can live with yourself with 0%. With 0.000000001% you will go insane. Eventually. Perhaps right now your mania of dedication you view as productive and healthy instead of insanity. But one day the charade falls and your life which you dedicated to that chance falls with it.
When I had a waifu, I used to wish how wonderful it would be if she was real, how I'd do everything in my power to get her and be with her no matter what. Now that I'm madly in love with Vtuber, I can confirm that wish was perhaps the most stupid I could've thought of. I have no excuse to avoid trying my best, but I'll still lose. And when I lose, I lose everything meaningful I had left, and have no-one else but myself to blame.
