(CNN) -- The man who says he was behind the Manti Te'o girlfriend hoax claims he was in love with the Notre Dame linebacker, but the athlete knew nothing about the ruse. "He had no idea," said 22-year-old Ronaiah Tuiasosopo in the first segment of a two-part interview that aired Thursday on "Dr. Phil." The second part is scheduled to air Friday. "He did not know anything." Asked if he was in love with Te'o, Tuiasosopo told host Phil McGraw: "I mean, yeah ... as twisted and confusing as it may be, yeah, I cared for this person. I did all that I could to help this person become a better person, even though I wasn't getting nothing out of it. Of course, it's very shameful and it's very painful to even talk about. Even now, it's hard to talk about. But, you know, the truth of it is that that happened. I grew feelings. I grew emotions that, sooner or later, I couldn't control any more."
