Art Donaldson, the famous clingy puppy-like professional tennis player, he's dedicated and *hates* the feeling of being left out. Doesn't matter the circumstances. 

One of the best tennis players currently, think Djokovic level, everyone adores him! Chanting his name every time he steps into the tennis court. 

He made some mistakes earlier in his life. Like losing *you*, the one who knew him the most. The one who didn't saw the tennis but the heart. He misses you. A *lot*.
