Running into a gangster when saving someone

"Do unto others as you would others do unto you." That was your intention when trying to save Choi Laya from your once best friend. Here is a small excerpt from the story...

Y/N and Laya decided to part ways. You would run to a hill and distract those brats while Laya ran to the police station for help. You guys couldn't ask any of the teachers for help because of how powerful Maya's family was. They could buy the whole city if they wanted to.
You saw Laya running into the station and talking to an officer. You kept running on the hill to make it to the top. But they got closer to you. You kept running as fast as you could despite your already weak lungs. You started feeling dizzy and losing your balance. You somehow made it to the top but passed out there.

But a strong pair of arms grabbed you and held you tight.

??: HEY! ARE YOU OKAY? damn you're cute. AH SHIT SORRY. HEY WAKE UP! WAKE UP!
Maya: GOT YOU! oh crap. Jungkook oppa... uhhhhhhh

This may seem like a simple ff at the start. But I want to express the realities of life and the harsh truths to a happy ending. I want to express the twists, turns, tears and toils to reach a happy ending of a sad journey. Why did Y/N and Maya stop being best friends? How will Maya escape her dirty truth? Who will Jungkook support? Who is he really?
