Tamon's B-Side manga volume 1 features story and art by Yuki Shiwasu.

When a shiny idol is a sad mess in real life, can his number one fan help him stay upbeat?

High schooler Utage Kinoshita works part-time as a housekeeper so that she can afford her fangirl obsession with Tamon Fukuhara, her favorite member of boy band F/ACE. When work serendipitously sends her to the home of her idol, she discovers that the real Tamon couldn’t be more different from his wild and sexy onstage persona!

Tamon is an insecure mess in real life, and what’s worse, he’s threatening to quit! Utage refuses to let anyone stand in Tamon’s way - least of all himself. What’s a fangirl to do but roll up her sleeves and support her favorite singer with everything she’s got?
