[ABO Cinderella Gender-Bender Fanfiction] Stepsibling

[Dual male leads + both each other's first and only + sweet romance and angst + palace intrigue and aristocratic families + evenly matched]

A restrained, cool-headed, scheming Alpha stepbrother × a clever, calculating Omega Mr. Gray who doesn't say what he means

One-line summary: What if Cinderella were a scheming boy who was sweet on the outside and dark within?

Mr. Gray, Louis, is bullied by his stepmother and two stepbrothers, so he decides to fight back.

He plans to get the formula for Honey Essence, a banned substance that can disguise one's pheromone identity, ruin his stepbrother's business, restore the glory of the Mott family, and drive out his horrible stepmother and stepbrothers!

But just as a confident Louis takes his first step, he's framed and left with no choice but to accept a deal from his stepbrother Philip. The two become partners in the banned-substance trade.

As Louis stays on his guard, he gradually realizes that Philip's feelings for him might be more than brotherly.

They use one another and test each other. Two clever, cautious men can only keep getting closer under the excuse that it's “for business.”

Then an invitation arrives to a ball hosted by the kingdom's Alpha princess. As midnight strikes, they must make a choice.
