Seventeen's Seungkwan, I really enjoyed watching his polite 90-degree bow.

Manager Boo Seung-kwan took some time out from filming to stop by the movie theater. Boo Seung-kwan told Kim Yeon-kyung,

“Hello, brother,” he said, bowing politely at a 90-degree angle.
Kim Yeon-kyung greeted him warmly, but joked, "You dyed your hair? You look like an idol. Why are you like this?"

It made me laugh. It was so nice to see! Haha
