Super Junior Kyuhyun & EunHyuk talk about Seohyun's Birthday Party Story on Strong Heart next week.

In Kyuhyun's board, he wrote 'Eunhyuk is a bad guy'.

Kyuhyun said : "Seohyun & Eunhyuk sat there first."

And he was like: "Just thinking about it makes me angry"

Jealous much, Kyu?

Did you want to be the first man to attend her party instead than Hyuk?

That's why your board stated like that? keke
