Kikwang commented, "It's been awhile since our members known each other. It really amazes me that you don't use improper honorifics." Dongwoon responded, "It's just comfortable for me this way." Kikwang continued to express amazement, and said, "We've been together in the same group for the past 9 years. We're closer than just friends and have a tight bond of our own. If I was in your situation, I would've preferred improper honorifics no matter if I'm hyung or dongsaeng."

Dongwoon then provided an explanation, and said, "I don't think the use of improper honorifics determine the closeness in a relationship. If the dongsaeng drops honorifics, the way the message is delivered can be perceived in a hurtful way. As a dongsaeng, I want to keep a good balance."
