Lee Sung Min, who worked with Siwan on tvN's 'Misaeng' (2014) and is currently working with Junho through 'Memory', answered, "I was very comfortable with Siwan. With Junho, I feel more thankful. In 'Misaeng', I appeared as a mentor figure to Siwan. But in 'Memory', Junho is more like my aid. When I look at Junho through Tae Suk's eyes, I feel like I have a reliable donseng. He's someone I can depend on. Even yesterday, when we were filming face to face, I was a patient. So he looked after me quite well." 

The actor continued, "In 'Misaeng', there was a scene where Siwan looked at me with hearts pouring out of his eyes, but I think I get hearts in my eyes when I look at Junho these days. He's the most refreshing character here. He's killer." 

It seems like Lee Sung Min has great compliments toward both idol-turned actors!
