This HaBO request is from Anna, who wants to find this romance:

I’m looking for a book where the hero is a grumpy professional athlete, possibly named Will. He is taking temporary guardianship of his half-sister, who might be named Ruby. He treats the little girl with distance, but the heroine makes him realize that what he is doing is what his father did with him.

There was a scene where he has this epiphany. The little girl tried to do many things with him, but he rejected her. He told her to be quiet and go to sleep on your own or we won´t do ____ anymore (things like that, I think it was running in the mornings but I’m not sure ) and one time he entered her room and she was awake but making no sound.

I think the heroine was not from the city/town; she was on vacation or on business (her being there was only temporary).

Does this sound familiar?
