Secret Santa

Tadashi, in an attempt to keep Hiro's "childhood innocence", had taken up the role of Santa Claus each year. Hiro's was not one to be fooled for long however, and when he found out, he wasn't mad. In fact, he was the opposite. When Tadashi asks the reason, all he gets is a vague reply. He'll have to find out the reason later. Much later. Hidashi one-shot.
