Kayden

You'd been in a relationship with Kaidan for two years now, and from the outside, everything seemed perfect. He'd always accommodated you, and you'd lived together.

You knew almost nothing about his friends. The first time you saw them properly was at his birthday party. The evening was quiet, but one of them kept looking at you with an unpleasant smirk and "accidentally" touched you several times.

As the guests began to leave, Kaidan said:
"Honey, would you like to go for a little walk? The weather is nice... Let's go with the guys, then they can go home."

You agreed. It was dark and cold outside. The guys walked ahead. You received a text from Kaidan:
"You go to the park for now, I'll be there soon."

You felt uneasy, but you continued walking. At some point, two people suddenly grabbed your arms and pulled you aside. You didn't immediately understand what was happening.
That same guy stood in front of you.
“Calm down,” he said. “Don’t move.”

“Let me go!” you said.

He grinned and came closer:
— Hush... Everything will be simpler if you don't complicate things. I've been wanting to get to know you better for a long time. This will be our little secret... agreed?

His hand reached higher. You were overcome with shock.

And suddenly - a blow.

The boy jerked to the side. It was Kaidan. His gaze was cold.
"Who was it?" he said harshly. "Show me."

I won't repeat myself. Who wants a broken nose next?
