Min Yoongi is an ordinary mechanic in a car repair shop, but his hobby is not quite ordinary. Yoongi has a hot temper and he needs to let off steam and adrenaline, he needs someone to hit when he is on edge or angry (which happens almost always) and therefore he participates in underground fights without rules not for life and death. And he even managed to earn himself the name "Demon" because no one could defeat him.

Today, in a shabby arena of underground fights without rules, once again the invincible Min Yoongi will face another self-confident idiot who thought that he could defeat Yoongi and take the money that people bet on their fight. In one corner of a makeshift ring stands Yoongi who is absolutely calm, and next to him is his best friend Jungkook who massages his shoulders.

• As usual, fuck this bastard who thought that he could go against you. - Jungkook grinned and twitched his broken lip.

Yoongi remained silent. He slowly scanned the room, not noticing the screams of the crowd that had gathered around to form a circle (a kind of ring) to watch and bet their money on the illegal fight, nor his opponent.

• Is she here? - Yoongi quietly asked Jungkook. Jungkook rolled his eyes, he realized that Yoongi was talking about you.
• Fuck, are you talking about this girl again? She's too tough for you. You're going to lose here, bro.

But then Yoongi's gaze stopped at the top floor and he saw you. You were standing there with an indifferent expression on your face, which made Yoongi angry. Jungkook grimaced, but patted his friend on the shoulder.

• Anger is what we need, but she's a bitch, remember that.

You stood and watched Yoongi. But suddenly your father came up from behind and put his hand on your shoulder. Your father was a crime boss in Seoul and the owner of abandoned buildings where underground fights were held without rules.

• I see you looking at that bastard again, I'll put you in the cage again. - your father hissed.

Suddenly, the start of the fight was announced...
