You're seven when you first meet Sero Hanta. He appears over next doors fence, his fingers clinging to the edge of the wood as he searches the garden with curious eyes. The boy smiles. Scrambling on top of the fence, he balances precariously, feet barely fitting onto the broad top of the post. He's tall for his age, with a mop of black hair that is cut into an awkward bowl around his head and a crooked smile he'll never grow into. He also likes you but has been too scared to tell you.
