Since Shi Shu was a child, her parents worked outside the home, so sharing her thoughts with netizens through the screen was her way to fight against loneliness. Until she finally graduated from college, she was forced to move in with the daughter of her mother's best friend. The moment she opened the door, she was stunned: in front of her was her cold-faced sister Gu Tinglan, who was slightly raised but not sharp at the end. Instead, she seemed a bit alienated. After living together, Shi Shu discovered that Gu Tinglan was not as cold as he appeared. He would silently put her favorite strawberry milk in the refrigerator, knock on the door and hand her warm milk when she stayed up late for online dating, and even ask her quietly "who is the other person" when she was chatting with netizens. There was a possessiveness in her eyes that she couldn't understand. It wasn't until an accident that Shi Shu discovered that many things were not coincidences...
The idea: to use the cohabitation setting of "non-biological sisters" to break the stereotype of "cold personality = indifference" - under the restrained and alienated attitude of the cold sister, there is a heartbeat that has not been said for many years; in the liveliness of the online dating sister, there is a desire for companionship, and to use delicate daily life to show the multi-faceted nature of "love": both the tension of possessiveness and the gentleness of the flowing water.
