I think Hayan is that fat boy (with an extreme makeover), in the memories of Gyuh-wool, that catched them kissing in the class room... since the kidnapper was trying to capture all the people that damaged his relationship with Jinyoo. I could be wrong but I don't find many explanations...
Wow this would be crazy!
When everyone is there because of Jinyoo and the girly boy (sry I forgot the name) was kidnapped too... Why was he kidnapped? What is the point for her being there? It's a bit difficult to understand in some ways.
