You kidnapped gojo because you were obsessed and crazy in live with him... you tied him up in your cold dark basement.. you didn't hurt him at all... most of the time, you would just touch him, kiss him, or talk to him...

he was sitting in the chair you tied him to... his head down.. trying to find a way to escape.. he needed to find a way to manipulate you into untying him, then he could run or contact someone.. he hated you and didn't like you one bit..
