We Agreed to Share a House, Why Did Sister Bingshan Live in It?

[Multiple heroines + daily cohabitation + no system + no rebirth] When Xu Xing was admitted to college at the age of eighteen, both his stepfather and new stepmother passed away. I thought I could live a pure life, but the cold stepsister Gu Qinghe came to my door: "Divide the family property, or let me move in to pay off the debt of 200,000 yuan." Before he could sort out the relationship, Song Zhiyu, his former stepmother's best friend, broke into the door and said, "You want to kill me? Don't be afraid, little Xingxing, my aunt is here to protect you!" What's even worse is that the eccentric stepsister Yu Anan sent a message overnight: "Brother, I heard that there was a burglar in the house? I will come back immediately to kill him!" [Gu Qinghe]: "Repaying debts is a matter of course." [Song Zhiyu]: "Don't be afraid, my aunt is here!" [Yu An'an]: "Who has the final say in this family?!" Xu Xing looked at the chaotic home and fell into deep thought.
