Dayym, thats a whole new level of crazy.
Lying like that - for such a long time, for such an amount of money. All that money could've been invested in the kid's education, for example.
I don't even know what to say. Except that it's (most likely) not worth it. Maybe it was positive at some point, short-term, cutting the bullying of that kid at school short or whatever.
But the looming emotional havoc of that massive lie construct being discovered - I wouldn't say it's worth it.
The older that girl gets, the more likely she would start asking deeper questions about that "dad", his "life, when he's away from her". And at some point, the lie would automatically get out of hand.
Besides, with all that daydreaming, that single lady would never find an actual real partner.
Then again, I'm not informed enough about japanese societal culture and the "dating chances" of childed singles there, so not sure on that statement.
And, of course, again the famous "WHEN the girl has kids of her own". Not "if" This ObligationLifeScript thing is so prevalent in all cultures, that it makes one depressed.
