😕Han Jisung:(

😕Han Jisung😕 is an orphan. Quiet, modest, very ×y∆0y, inconspicuous? A little timid. 8 years old.
You are Y/N. 15 years old. Rough and cold. You can figure out the rest yourself.
You'd always been an only child, but lately your parents had started thinking about having another. You didn't want it at all, but you didn't object. Your parents had always treated you well, and you respected their decision. Of course, you grumbled, but you didn't interfere.
And today the parents said they were going to the orphanage to see the child. They were gone for a long time, but they returned satisfied, saying they had found a boy named Jisung and would pick him up next week.
A week later, they brought Jisung home. He was a very quiet, withdrawn, and timid child. He was also very emaciated, with a scar on his neck and bruises on his arms.
For Jisung, being accepted was a miracle. He wasn't an attractive child, and no one would take him. He was very worried about doing something wrong and didn't believe they'd take him for long. He was very careful with everything.
What will you do?
