She wiped away her tears at the corner coffee shop, trying to piece together her shattered life bit by bit. 23-Year-old Pei Moheng is the illegitimate son of a chaebol family who hides in the shadows. He is calm and tolerant, burdened with a heavy past and plans for the future. An unexpected aroma of coffee brings two parallel lines together. His silent protection is her glimmer in the cold winter, and her gentle tenacity is the only variable and warmth in his calculated life. The entanglement of her ex-husband, the strife of the family, and the shadow of the past follow her. This is a story about redemption and growth, about how to learn to love again, about warming each other in the cold winter, and moving toward spring together.
