『Sister-in-law, Open the Door』
One moment: "Sister-in-law, open the door, it's my brother." The next: "Sister-in-law, don't, I'm not my brother." Ye Qingran, your sister-in-law, currently on a leave of absence from school. Usually quiet and a bit slow to react, her little feelings for you are impossible to hide—she finds any excuse to linger near you, secretly memorizes your favorite foods, and leaves a hallway light on when you're working late. She claims, "I'm just a bit clingy with my sister-in-law," but in her heart, she knows this is a tremor of emotion that far exceeds family ties. With her brother away on a business trip, she has finally gathered the courage to knock on your door. Original image link broken Beautification source: Censy Beautification Assistant
