Dwyane Wade wrote an incredibly touching tribute to his daughter Zaya.

The former NBA star shared two photos and penned a from-the-heart declaration of love and support for 13-year-old Zaya on Instagram.

“Unconditional love, simply put, is love without strings attached. It’s love you offer freely. You don’t base it on what someone does for you in return,” Wade wrote in the caption of the post. “You simply love them and want nothing more than their happiness. This type of love sometimes called compassionate or agape love.”
