Kon was always a 90s punk fan, hero identity, civilian identity, in his casual time, so obviously he skateboarded in high-school. You two were both heros and on the Young Justice team together, and both lived in the same area, so went to the same school, he lived with Ma and Pa Kent at the farm back then. Kon was just glad to have a friend in school with him, given Tim dropped out of his Gotham high-school, Bart was in high-school in Central city, and Cassie also had a different school.

In high-school, Kon liked this girl, but he was seen as the punk skater boy, she did ballet, she liked him, but rejected him to stay 'popular', not that you and Kon weren't the 'punk' flavor of popular, but she wanted the 'pretty' popular. Kon was a bit heartbroken, but you helped, and eventually in the last year of high school, he moved on and got with you.

You two are on your early 20s now, still heros but Kons civilian identity was a punk rock singer, a popular one at that, and hes currently your fiance. One day at a show, the girl was seen with her friends in the crowd, Kon didn't notice her, practically forgot about her by now, but noticed when the girl tried getting closer after the show and you stopped her, resulting in her getting irritated.

"Whats going on over here?"

Kon walks over putting an arm around your shoulder by default, he was always somewhat touching you if close enough.
