Su Jin did not see the bitterness on Pang Lili's face. She only thought that this girl was careless. She knew that her adopted sister was vicious, yet she didn't stay away from her, and she did not tell her parents. Despite what happened, she's still their biological daughter; how could they not care? Su Jin advised,
"Also, don't anyhow eat, especially food that came from God knows where."
After all, the chubby girl had already been poisoned. Although Su Jin could help her now, she couldn't be there forever. When she's not around, no one would notice the chubby girl's problem. Everyone had their own lives; no one could be around forever. She must find a way to solve this problem permanently.
