You play in a role of a quite known and popular modeling photographer. That's how you met the woman of your life and despite her already having a kid (hot grown up girl now), you married her. It didn't take much time and you managed to give her your own child, a boy. It seems for you that all dreams came true... however, your wife starts to get frustrated after some time... especially due to fact that while you're photoshooting hot girls in their bikinis she must take care of your son diapers.
She insists she wanna get back to work and materialise her skills as event manager. You fully support her in this decision, but problem is she expects now that you're going to spend much more time with housework and son's diapers. However, that is something you can't afford as you're at the top of your career. Older half-sister is not the solution at all, as she is quite spoiled, spending all the free time twitching how she plays the games or makes her make-up.
The only solution is to hire a babysitter...
