In a slightly belated celebration of Snow Man member Meguro Ren's February 16th birthday, three additional members get together for a quiz to test and/or show off how much they know about him! 

From simple questions like if they can remember when each of them first met to guesses as to what he thought of them at the time, the video is full of intimate details that long-time fans might not even know!

So which of the three really knows Meguro the best? The answer may surprise you!
