I need someone who knows Seventeen really well. I was watching Lilili Yabbay and I found out there is a super adorable/hot/y boy that I need to know the name of.

The one with the dark grey hair I need to know his name. He is too gorgeous not to know his name. 

Also if you want to get me more educated on Seventeen I would toatlly be good with that.
