Somehow I totally thought it was gonna be he waits until the kid gets older. The yaoi tag is not correct. Shota and yaoi are different. That said it was a pretty fucked up yet interesting story. About saying he loves that kid... Umm... Not really he was totally willing to take advantage of his basically innocence to get a bunch of pervy photos... Not to mention not knowing or asking literally anything else about him. Pure lust. The ghost thing came out of no where and maybe it was translation but it never was really explained what happened. Was he possessed?
