Mira and Jonas have rules for loving each other.

They are not about passion or fidelity. They are about survival. About how close you can stand to someone without losing yourself.

When Mira introduces a fourth rule, it feels reasonable. Necessary. Until fear turns care into control, and the rule is broken.

Set in the quiet intimacy of an apartment where every glance and silence carries weight, Breaking the Fourth Rule is a slow-burn, emotionally intimate romance about boundaries that deepen passion, love that refuses ownership, and the rare courage it takes to choose each other, without giving up yourself.

What happens when love survives only if both people remain whole?
