Wheein appeared on Mnet's "M Countdown," which aired on January 27th, and was honored with first place with the title song "Make Me Happy" of her second mini-album "WHEE."

Wheein proved her hot popularity with brilliant performance of No. 1 for the first time since her solo debut with Make Me Happy.

After winning first place, Wheein said through her agency The Live, "Thanks to the staff who agonized and suffered together, I was able to work happily. I love the members and family a lot. In particular, I will become a person who keeps the valuable award given by our MooMoo (MAMAMOO's official fan club) in my heart for the rest of my life.

On this day, Wheein caught the eye by showing off her unique charm by perfectly wearing a red checkered outfit. The pink-colored stage set made Wheein's splendid visuals stand out even more.
