With just one day before INFINITE's comeback, they have released last member Sunggyu's video teaser.

In the teaser video, Sunggyu is seen on a rooftop preparing a special event for the woman that he loves. While he is working on the event, he is seen smiling, showing his excitement.

On March 21, INFINITE will be releasing their new title song, "Man in Love."

As a way to celebrate with their fans, they will also be holding a D-day promotion.

Individual video teasers and posters have been released one by one until the release date.

They will be holding a press conference tomorrow and officially begin their comeback activities.
