Am I Wrong to Reject the Aloof School Belle's Proposal?

To smoothly inherit a top company, Asano Aki spent his entire youth keeping a low profile. Who could have guessed that the aloof new campus beauty would propose to him in front of everyone?

"I know your secret. Now you have no choice but to marry me, Demon Lord."

"Great, but I refuse."

He had almost made it through all those years of keeping his head down. There was no way he would let this woman ruin his peaceful life!

But from then on, the famous idol who fell in love with him at first sight, the mature teacher who had coveted him for ages, and the pure-hearted class beauty who had once confessed to him... all started chasing after him.

Asano Aki was baffled. What on earth did I do wrong by turning down the aloof campus beauty's proposal?
