INFINITE's Woohyun and SHINee's Key's unit Toheart will make the women go wild with their song "Delicious".

Toheart's first album title song "Delicious" is a pop and punk genre song that was released on the 10th via various popular music sites. The lyrics imply that Woohyun and Key are battling it out to capture one woman's heart.

Woohyun and Key sing from their own perspectives in the song, which is different from other same-sex duet songs that sing the same lyrics with different vocals. They instead give and take their own positions in the song, just like ping pong.

From the listener's perspective, it seems as if these 'delicious' charismatic men Woohyun and Key are fighting over them, and it's expected that the song will appeal to numerous female music fans.

"Delicious" is a work of hit maker Sweet Tune and famous composer Sean Alexander.

Toheart held their 'The First Mini Album' showcase "Delicious" on the 10th as well, and performed their first duet performance. The title song "Delicious" music video was also revealed there.

The music video featured Woohyun and Key's cartoon images transforming from children to boys to youths. It was directed by Hwang Soo Ah, whose previous works include IU's "Good Day" and Gain's "Bloom".
