Tenshi wants nothing more than to disappear into the background, but Haruo won't let him. The show understands that real courage isn't about wanting to perform, it's about showing up anyway, even when your voice shakes. By the finale, you're not watching a choir win a contest; you're watching five guys learn that being heard matters more than being perfect.

Tenshi loves to sing, but actually doing it in front of other people is more than he can manage. So he has settled for a quiet, low-stress school life, keeping his passion to himself. That changes when Haruo barrels into his world with a proposition: join a brand new boys choir. Haruo has his own reasons for starting the group, mostly involving his reputation and a way back to his old job. What starts as reluctant participation transforms into something genuine. Tenshi and his fellow members come to love performing together, and winning the national choir competition becomes their goal. The show pairs that musical journey with plenty of comedy.
