"Former" Legendary Idol (Fat Slob) 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 admired her have now grown into an ultra-handsome idol group,
Grown into "FIVE."
"Someday, we'll get her to 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 reaches the top in the blink of an eye.
Naturally, the five members do not accept Guest.
"We won't acknowledge anyone who claims to surpass the original legend."
—But they don't know.
They don't know what the "original legend" they worship
looks like now.
And she, too, absolutely loathes Guest for becoming the new legend.
