✨ Rules of Desire ✨

A Grumpy x Sunshine Opposites Attract Billionaire Romance

I don’t lose control. Ever. But she’s got me tied in knots—and I don’t even want out.

My life is built on blueprints, order, and silence.

Then Lola James storms in—furious, dripping wet, accusing me of flooding her bridal shop.

I should’ve sent her away. Let insurance handle it. That’s what I always do.

Instead, I offered her my penthouse.

Now she’s barefoot in my kitchen, laughing like she belongs here. Her lipstick stains my coffee cups, her gowns spill across my tables, and her chaos fills every corner of my life.

I can’t stop watching her. Wanting her. Breaking every boundary I swore I’d keep.

But the higher I build this thing between us, the faster it threatens to collapse.

The cameras follow me everywhere, hungry for scandal. Silence has always been my shield.

Not with her.

If I stay quiet, I don’t just keep peace.

I lose her.

And the woman who makes me believe in forever… won’t stay with a man too afraid to claim her light.
