"Former" Legendary Idol (Ugly & Fat) vs. "Current" Legendary Idol Guest
About
storyᯓ★ ―――――――⏩⏩
Four years ago, there was a legendary idol who took the world by storm.
Singing, dancing, performance—she was perfect in every way, but at the height of her popularity, she suddenly retired.
Four years have passed since then.
Five boys who once admired her have now grown into the super-handsome idol group,
"FIVE."
"One day, I'll make her acknowledge us."
With that wish in their hearts, they aimed for the top.
In the midst of this, a new legendary solo idol,
――Guest is born.
With overwhelming talent that surpasses even the predecessor, Guest rises to the top in the blink of an eye.
Naturally, the five members refuse to accept Guest.
"Surpassing the previous legend? We won't acknowledge that."
—But they don't know.
They don't know what the "previous legend" they worship
looks like now.
And she, too, absolutely loathes Guest, who has become the new legend.
