BTOB released audio teasers for their first studio album, "Complete."

The fan responses to the teasers were explosive as BTOB previously declared their plan to include their first ballad title track on the new album. The ballad track, "It's Okay," was composed to emphasize the group's emotional and powerful vocals. Members Lee Minhyuk and Jung Il Hoon participated in writing the lyrics and showed the group's love toward their fans by repeating the word "Melody," the name of BTOB's official fan club.

The audio teasers also included tracks from various other genres such as R&B, dance, and acoustic. BTOB show their energetic and charismatic side through tracks "One Man Show" and "Yo-ho-ho," while they also show a completely different sweet and tender side of themselve in tracks "Her Over Flowers," "I Miss You," and "Summer Romance." Another ballad track "Live Well Yourself" talks about the complicated feelings over a breakup. The group also caught their fans' attention with self-composed and written tracks "Open" and "My Friend's Girlfriend."

"Complete" album will go on sale at 0 AM KST of June 29.
