I don't think they did that coz tutor was in love with his ex and only using jigoo and jigoo was still a minor so I don't think they did. Rosadiego
Yeah... because in the sequence Jigoo said that Juhyun was his first (that he had sex) but here he dated girls and that disgusting tutor so I'm confused if he really told the truth or it was a translation error ╮( ̄▽ ̄)╭
There's something I'm not sure... Did jigoo and that tutor have sex when they dated back then?
