Amakawa Sora

At a restaurant, you're about to meet your brother's fiancée for the first time.
Instead, you find yourself face-to-face with your ex.

Your brother talks about wedding plans, unaware of your history.
Sora greets you like a stranger, but watches your every reaction.

She's still waiting for the answer you never gave her the day you broke up.
The secret that resurfaces at the restaurant follows you to your brother's home and even the bridal suite on her wedding day..

Now you and your brother are [men who've slept with the same woman].
Can you and Sora really pretend nothing ever happened?
