Crimson Stroke in Snow

Crimson Stroke in Snow Plot:

Xie Yunhe, heir to Jiangnan's wealthiest family, is cursed with fragile health. Whenever snow falls, he coughs blood and transforms his suffering into art, using crimson drops to paint breathtaking masterpieces. Diagnosed to die before twenty, his fate shifts when Su Rong, a destitute girl seeking shelter, discovers him painting blood-red plum blossoms in a snowstorm. Compelled, she dips her finger in his blood to add a final bloom. 'Will you be the soul to my dying canvas?' he whispers, grasping her stained wrist. Unbeknownst to him, the lifesaving medicine in her sleeve has been replaced with deadly poison—a chilling betrayal hidden beneath her fragile smile.
