Some people collect stray pets out of kindness. Others adopt stray human adults out of guilt. This marriage gets upgraded, not with a puppy, but with a full-grown stepson and his partner, both finally running out of options after years of haunting someone else’s basement. The ex-wife retires as their reluctant landlord, and the new invitation drops without warning, like an unexpected thunderstorm, one that promises a forecast of slamming doors and extra laundry.

And so, the world’s coziest rescue shelter hosts two difficult personalities who would probably argue over how to split the air in a small house. Husband claims the spare bedroom is charity, not chaos, blissfully ignoring the volume level of «not getting along» and the recurring fantasy of shared retirement with zero privacy.
