Mario has just recently made his comeback with "MAYDAY"!

"MAYDAY" is an international radio distress signal, and in the song, Mario is asking to be saved in the midst of the summer heat.

The track was written by composer Choi Yong Chan and rookie composer Seo Yong Bae who wrote Ailee's "Heaven", and has been in the works for the past year.

Mario has personally participated in writing the witty lyrics, and with his refreshing vocals, Mario will be captivating the ears of the listeners who are weary from this summer heat.
