That was a bad translation, members here who knows more about it says the correct translation is that the Soul King has an interest in Ichigo, IMO suggesting that he's curious about Ichigo, or something like that.

Seeing as how Ichigo is a human with Quincy powers, a Fullbringer for a short time, and his soul form is a Shinigami with an inner Hollow - which also happens to be his Zanpakutô - it's logical. He seem to be the first person ever in the Bleach universe to be all of those races in 1 being. Also seeing how Hollows are poison to Quincies, and that Shinigami are enemies of both Hollows and Quincies, it's an interesting mash-up.
