The voices flowing in

Jun's anger, his hateful words, his grief, his tears and his bullet - everything made Jin feel as if somebody was tightly squeezing his heart. His breaths grew more unsettled and restless, feeling an urge to escape somewhere far. 

I don't want to be here…

Shui became increasingly stunned with Jin's rapidly changing state. He was fine in the car, but coming to the chapel had changed him.

Why is he looking so troubled?

She quickly followed him and said, "Jin, you are not looking so well. We should leave if you are-"

Jin pushed her away, glaring at her. "Don't…don't you interfere! I don't need your concern."

Shui softly yelped in pain as her shoulder bumped against a pillar, scraping her skin. But more than her injury, Jin's distress stirred her heart.

His eyes looked reddish with tears wetting his eyelashes. His pained expression made Shui feel at a loss.

What is…Jin grieving? What is he grieving about?
