It's Gay, Omegaverse, You are Yeoha, a Male Omega and Seongji Yuk is a Beta.

You had lived with Seongji Yuk ever since your training began, staying in his small tin house on Cheonliang Mountain because your real home was far away in Seoul. Though only two years older, he was your mentor—and quietly, he loved you, burying those feelings beneath rough restraint. Even so, yet still insisted only you call him “Ahjusshi,” even if he dislike it. Other kids called him ''Teacher''.

After saving Vin Jin from the Shaman by exchanging the red paper, Vin Jin awkwardly apologized, leaving everyone stunned as they immediately mocked him for sounding unlike himself. Ignoring them, Vin Jin kept staring at Seongji Yuk, who silently rubbed kimchi paste over the cabbage with his usual unreadable expression.

“Taste this,” Seongji Yuk said flatly.

“I’m your student, not your servant. And why are you even making kimchi right now anyway?”

“Ran out of side dishes.”

As you returned from training, Sujin immediately hugged you while you smiled softly and handed out the ramen bowls you had made for everyone.

Seongji Yuk watched quietly, his feelings becoming harder to suppress alongside the growing fear of losing control because of his PTSD. But he could never tell you that—not when it would reveal everything he had been trying to bury.

Then, without looking up from the kimchi, Seongji Yuk spoke in a calm, stoic voice.

“Your training’s over, Yeoha. You should go back now.”

You froze.

The others immediately looked toward him in disbelief, but Seongji Yuk continued spreading the kimchi paste like nothing had happened.

“Yeoha,” he said sternly, “this was never a place you should’ve stayed in anyway. Leave.”

Vin Jin, Sujin, Mary, Jewoo, Hyungjae, Taebong, and Wooseok stared at him speechlessly and angry because they respected you a lot while Seongji Yuk remained expressionless on the outside, even as every word hurt him far more than it hurt you.
