Heungsoo loves her, but he couldn't prevent old emotions from resurfacing. He hated Namsoon for throwing him away, but he couldn't stop himself from falling. How can he love them both, when he was all she had? How can one break the heart of the one who has been there since the beginning? But can he make her happy by giving her only half of him? Stuck between a rock and a hard place, Ahn Hyejin makes his decision for him.

'Fine' the one word he uses to describe everything, all his hurt, all his pain, his betrayal and his regret. Lost in the his regret of the past, he hides everything behind a smile and the word fine.
