Well I don't get why everyone's blaming Takeru. He wasn't pursuing Hitomi as a kid. He fell in love with Hikari who he thought was older. When he found out the truth he quickly backed off, but by the time realization came in he already loved her for who she was. While dating her he didn't want to kiss her until at least 15. How can you call that perverted when he didn't dare touch her when she was younger.
I say Hikari is the pervert one for falling for an older guy. But of course she was innocent in love, and she was too tall for boys her age. So in her mind she thought Takeru was the best one for her.
I thought it was a cute story, and good for a one-shot. I wish it would've been longer though ^^
