Shin Ryujin has always played it safe-building walls, keeping her distance, and doing whatever it takes to avoid the chaos of emotion. But when her latest attempt to escape her problems only leads her deeper into grief, she finds herself reluctantly starting over at Shin Hwa High. There, she crosses paths with the infamous F4-four boys known for their charm, recklessness, and unbreakable bond. They are everything Ryujin is not: bold, unapologetically emotional, and dangerously free. Especially their enigmatic leader, whose presence both infuriates and disarms her. As sparks fly and tensions rise, Ryujin is forced to confront the truths she's buried for so long. But can the people she's spent her whole life avoiding be the very ones to help her heal? Sometimes, the only way out is through. But will Ryujin dare to let someone in before it's too late?

For the first time, he's getting acquainted with love, or so he thought. Like a cold winter dream. Never ending. Never warm.
