'Hyung Don and Dae Joon' might be going through a style change soon.

Member Defconn (Dae Joon) tweeted, "If 'Hyung Don and Dae Joon' are going to sing this winter, our clothes are going to be a problem... If we sing outside, we'll freeze immediately. We have to prepare duck down jackets before it gets cold. Jack Nicklaus, Wolsey, Big Gate or Nova is good," making fans wonder if 'Hyung Don and Dae Joon' will be making a comeback soon.

He also attached a photo of the duo's first album cover, which reveals the short sleeve ahjusshi look the two have been promoting with. However, as the weather is getting colder, Defconn seems to have decided that it would become impossible to promote with the same style, hinting at an upcoming wardrobe change.

Netizens commented, "Are you hinting at winter activities?", "I'm looking forward to fun performances in the winter too!", and "Oppa, be careful of colds".
