Group Infinite's member Woohyun and SHINee's member Key will be releasing their song "Toheart" next week.

Woohyun's agency Woolim Entertainment revealed today that they will be releasing their song on March 10.

"Toheart" is a unit that the same-age friends Woohyun and Key created. The two have been on their own journeys of expressing their own character that other groups haven't shown before.
