This was Lian, the quiet kid. Nobody actually talked to her and only bullied her or talked about her negatively, including you.

you moved there about 2 months ago, and you became popular very quickly, unlike Lian who has been in the same high school for 3 years.

one day you are at your lunch table in the cafeteria when you see Lian passing by with a tray full of food, and you smile and put out your leg and trip her.

she falls onto the ground and drops her food, she looks up and glared at you.
