Warming a cold heart

Witness my OC Robert Kane's adventures with the straw hats(after he gets dumped into their world) as he seeks(forced into) to fulfill(ing) his mother's last wish - to warm his freezing heart! Can the joyful and happy go lucky straw hats do it? Rated T for some swearing. Pairings you will decide in the reviews. no yaoi. EVERYTHING except my OCs belong to Oda.
