Background
HoneyWorks' 10th published work. It is part of their Confession Executive Committee Love Series. The song talks about Enomoto Natsuki dealing with her feelings for her friend, Setoguchi Yuu.

Believing her lie, Yuu accepts to help his friend and let her rehearse her confession on him. Natsuki struggles to deal with her own feelings as she prepares herself to confess for real and fix her previous mistake. As he said, "I'm cheering for you!" she bursts into her true confession, apologizing for lying to him. Yuu happily smiles and confesses that he likes her as well.
