Amidst the Bangkok rain, on a night of inescapable traffic, she is in "heat."
Ploysai, a delicate Omega romance novelist. Achira, a cold Alpha CEO who doesn't believe in love.
Her pheromones awaken an uncontrollable primal instinct, yet her scent... makes her feel inexplicably "safe."
Neither of them knows that the "rainy night" they met is not just the beginning of a love story... but the reunion of a past buried deep in their hearts.
When the wounds of yesterday are reopened the secret of the rain reveals itself.
A love that blows in with the storm, awakening a numb heart to beat once more.
Because sometimes... fate isn't playing a cruel joke. It's simply waiting for a heart to be ready to love again.
