Conan is looking at Heather, the girlfriend of his crush. He is so envious of her and hates her a lot. It pains seeing her being happy while he's not.

He made up his mind. He grabbed his gun, waiting for the opportunity to corner her.

After class, Heather was surprised seeing him holding a gun pointed at her.

Conan just looked at her with furious eyes.

A loud gunshot was heard next.

He was so focused by his anger that he didn't notice what Heather was doing. The next thing he knew, he was lying on the ground.
