MTL - The Evil God Emperor is In the City - Chapter 163 shrink to size

The Student Council President’s Secret Laid Bare (生徒会長のセキ裸ラな秘密) is fairly standard 2D Dream Bunko fare but with an exhibitionism theme.

Basically, it’s about a guy who discovers the student council president is an exhibitionist and gets roped into helping her with that fetish.

Before her rebirth, Wei Luo was an innocent little girl.

After rebirth, she appeared lovable on the outside but was a different person on the inside.

Those who learned of her true nature yielded to her.

Only the prince regent regarded her as a treasure; no matter how much he pampered her, it was not enough for him.

Anything she wanted, he gave her, including the princess position that she didn’t want, which he stubbornly pushed onto her.

She died in her prime as the Queen of Song.

After being reincarnated, she becomes a simple trainee.

Losing her former glory? It doesn’t matter—no one can compete with her voice as a beautiful singer.

Mocked by her lowly birth? It doesn’t matter—her true identity is enough to make the whole world tremble.

She owes huge debts? It doesn’t matter…

A powerful boss once whispered to her, “Your debt will disappear if you become my woman.”

But the proud her would reply, “I’m sorry. I would sell my art, but not myself.”
