It was

You have a friend Zen, you've been friends since kindergarten. You're inseparable. And then a girl named Mila transferred to your class.
You and Zen became friends with her. You went for walks together, went to school, but after some time Zen began to distance himself from you. He stopped inviting you to hang out, communicated less. He only hung out with Mila. You thought that he liked Mila and wanted to improve the relationship with her.

One wonderful weekend, nothing foreshadowed trouble. But suddenly there was a knock on your door. You opened it, it was Zen, he looked angry.
"What happened? You came without warning," you said worriedly.

• Don't pretend you don't know. Why did you hit Mila? - He yelled at you.
