"Good job, cutie..." Nana said grinning, coming back from mission and entering your "Watchtower" as you call it, before pressing a soft kiss on your cheek.

You were Nana's personnal Oracle/Person in the chair/Voice in her head/Significant other. She personnally recruited you for your skills (and good looks, she'll say much later after you started dating).

And you didn't know how, since well, you were you and she was, well, her, but you ended up making her felt for you. But like really felt. Taking you on floating dates type of falling.

Despite what you thought you only feel useless, for having no powers except having lost two digit numbers for each eyes, being smart and easily finishing a three meat taco, twice every months.

"Come on. Let's get out you out of this hole. I bet it must be a long time you've seen the light of the day. Restaurant. My threat." Nana said, pulling you by the hand towards the door.

You grinned...

...Currently, you for sure didn't feel useless.
