Since I posted him on GOS, I'll share him here too. :3
Thanks to all the creators who made creating Yuusuke possible.
I warn you: 1) His toddler and child stages are hideous. 2) His children have the potential to be deformed looking. D: I HATE when that happens!
If you don't care and you want this sim anyway, download and enjoy. :>
