I Have Been Pampered for Many Years and You Call Me a Child Breadwinner?

[The introduction is weak, please read the text. [Yandere + Control + Pure Love + Older Sister] In the darkest year of Lin Tao's life, Su Qingxue appeared in front of him like a ray of light. She was wearing a black dress that day, and she had an aura that kept strangers away from her. But when she looked at Lin Tao, she had a slightly awkward smile on her face. "Will you go home with me?" Then Lin Tao was taken home by Su Qingxue. Lin Tao calls Su Qingxue sister, and Su Qingxue calls Lin Tao brother. But as time passed day by day, everything went wrong. "Let me ask you, who is that girl?" "Taotao, come back quickly, Mr. Su fell down." "I have difficulty moving now, so you can carry me to the living room." "Taotao, it's thundering today, can you stay with me in the room?" … Late at night, Su Qingxue looked at Lin Tao who was sleeping, with the corners of her mouth raised slightly. "So, Taotao, you can never leave your sister." "Even if... You lie, you will lie to me forever." On the bedside table, two marriage certificates looked so dazzling under the light of the bedroom.
