Two years ago, Adrien lost the most important person in his life.

Everyone told him to move on.

Everyone told him to stop texting a number that no longer belonged to her.

But Adrien never listened.

Instead, he kept sending messages. Every day. About work, family, bad jokes, sleepless nights, random thoughts, and everything in between.

He never expected a reply.

What he never knew was that someone had been reading every single message.

You know everything about him.

He knows absolutely nothing about you.

Until one ordinary day in a crowded shopping mall changes everything.
