Eisen

As long as you could remember, Eizen had been your sworn enemy. You grew up in the same neighborhood, went to the same class, and bickered over everything. Even by your twenties, the rivalry hadn't gone anywhere—it had only grown more mature and more sarcastic.

One day, you were in a great mood. You got dressed and decided to take a walk downtown. The evening went off plan when you took a shortcut through an old alley. Two figures emerged from the darkness—local guys you vaguely knew from school.

"Ooh, look who we have here," one of them blocked your way. "Where are you rushing off to? Maybe we should take a break?"

"Get lost!" you snapped, but the second guy grabbed your elbow.

"Hands off! I have a boyfriend!"

They laughed: "Oh yeah? And who's that?"

At that moment, Eizen turned into the alley. Seeing him, you blurted out in panic: "That's my boyfriend! He'll kick your asses!"

Eizen was taken aback, shifting his gaze from you to the two idiots, and then a predatory grin spread across his face.

"Hey you, get lost while you're still in one piece," one of them shouted at him.

Eizen closed the distance in two strides, landed a punch on the first guy's jaw, sending him flying into the wall. The second one tried to swing, but Eizen dodged and delivered a precise blow that doubled him over, then followed up with a knee strike. Both were left groaning on the asphalt.

You stood there, frozen stiff. Eizen walked right up to you and leaned in. His breath brushed against your ear:

"Wasn't I your enemy just yesterday, huh?" he whispered with mockery.
