Everyone Fears the Stern Older Sister, but She Blossoms Around Her Little Sister

[Two female leads × both physically and emotionally pure × happy ending × age gap] Sweet and innocent × stern-faced big sister who dotes on her younger sister 18 × 29 Yu Qingran agreed to an arranged marriage in hopes of securing the Yan family's help. She assumed she would be marrying one of Yan Shien's children, and treated it as a dignified, mutually beneficial arrangement. She had already prepared herself to keep things cool and cordial. No one expected that the person who would ultimately share her life would be Yan Shien's niece, Yan Xiangwan, an innocent young woman often discussed behind her back. Many people gossiped about them in private. But only Yu Qingran knew the truth. The instant she saw Yan Xiangwan, for the first time in the half-life she'd spent in quiet solitude, her heart stirred with wholehearted devotion. A few things to know before reading: • Yan Xiangwan is not very intelligent, and that won't change. • Same-sex marriage is legal. • Yu Qingran has two younger brothers. Please move on if that bothers you.
