Help with this title

I really stink at remembering titles so here the description.
Ok so the tall boy works for a jack of all trades company and he gets a request from a customer saying they want someone to hang out with them. Tall goes to the apt thinking it is a child, but instead finds a cute lonely salaryman . There is also another couple with a runaway young master who hates when people try to get with him and a private detective who was hired by the young boy family to bring him back.

Thanks either way! ╮(￣▽￣)╭
