The Promised Cannon Fodder? Why Does Your School's F4 Group Pamper Me?

Jiang Zhiyu has become the cannon fodder control group for the heroine of a bloody sweet novel... With no identity or background, and even his parents are not biological. She was supposed to set off the heroine's elegant and untainted temperament and was reduced to a background, but somehow she took away the plot that was supposed to be started by the heroine. The cold and abstinent F1 pulled her into his arms: "Classmate Jiang, I hope you will think of me as soon as you encounter difficulties." The unruly and arrogant F2 forced her into a corner: "I can help you with anything Lu Heng can do, and I can help you with anything he can't. Choose me." The gloomy and yandere F3 stroked her face: "Xiaoyu, don't look at them, you can only see me." The gentle and venomous F4 kissed her hand: "I will always stand there waiting for your favor and will not ask you to make any decisions." Aren't you the heroine's harem? Why do they all come to me? ! - Later she learned that these people deliberately approached her because of her relatives. The family members she thought were extremely ordinary were actually difficult to deal with. The gentle old man is ruthless. The taciturn old lady is unreasonable. She thought that her father, who was idle and had nothing to do, was an important figure... No wonder my mother goes out early and comes back late every day. Is it because she is running for her life? I thought it was a cannon fodder passer-by script, but ended up accidentally harvesting the whole family of villains? In this case, she would not refuse anyone who came. However, it was clearly them who approached her with a purpose in the beginning. Why did these people start begging for her sincerity later?
