Living together was supposed to be simple.

Riley came to Qingdao for his Master's degree in East Asian culture. A year of serious study, a new city, a new language, and a chance to leave everything else behind.

Then he meets her.

Zhao Yining is disciplined, guarded, always in control. She keeps her routines tight and her distance even tighter.

But in their small, shared apartment, distance is an illusion.

At night he hears her moving around, the soft sounds of her body shifting in the dark.
She notices when his side of the wall goes quiet, when his breathing slows and deepens.

Neither of them says a word about it.

What starts as careful politeness slowly turns into something charged and impossible to ignore. Shared glances linger a little longer. Late-night moments in the dark pull them closer, until the air between them feels thick with unspoken want.

In a space this small, you do not just learn someone's habits.

You learn their rhythms.

Their secrets.

Their weaknesses.

And eventually their desire.

Thin Walls is a slow-burn, emotionally charged novel about proximity, tension, and the dangerous intimacy of being truly seen, whether you want to be or not.
