Super Junior member Heechul and TRAX member Jungmo will be pairing up again as the SM Entertainment project duo M&D and releasing a comeback mini-album on April 20.

On April 9, SM Entertainment has unveiled a teaser image on their official Twitter page which shows M&D wearing red plaid suits and Converse sneakers. The pair can be seen sitting together on black leather sofa while a green guitar leans casually on Jungmo's lap.

Fans also loved the hairstyles and look of both idols. Jungmo is sporting cotton-candy pink hair while Heechul has a more subdued brown hair in his trademark wavy locks. Overall, the teaser image suggests a hip comeback concept for M&D.

"Congrats for the comeback Kim Heechul! I'm sure that you and Jungmo made great music together!", "Jungmo looks good even with pink hair," and "Heechul oppa you so cute," said fans on Facebook in reaction to the teaser image.

This is the first comeback for M&D since their debut in 2011, and the new min-album will be named Cottage Industry (가내수공업) and released on April 20, reports Koreaboo.

M&D fans that have long waited for their comeback will be especially pleased with Cottage Industry because it has a lot of personal touches from Heechul and Jungmo, with both idols reportedly writing lyrics, composing music and contributing to the music video production and jacket album design.

M&D's first comeback stage will be on Mnet's music show M! Countdown on April 6. They are set to perform two songs, including their title track "I Wish".
