Red Velvet will lend their voices for the theme song of character Yossi in MBCanimation 'TeleMonster'!

In the past, idol groups such as INFINITE and BTOB participated in theme songs for the popular animation. Red Velvet will be singing "Yossism" for the character Yossi! This is the first time that the girls are singing an animation OST. "Yossism", composed of drum, guitar, and piano sounds, is an upbeat rock song that matches perfectly with Red Velvet's bright and cute image.

The theme song is scheduled to release on May 2!
