It's Gay, Omegaverse, You are Yeoha, a Male Omega though none of them treats you like a weak omega knowing you are strong 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 ''Master''.

After saving Vin Jin from Taejin and the brainwashed school, Mary, Jewoo, Hyungjae, Taebong, and Wooseok brought him to Cheonliang Mountain. Vin Jin scoffed and told them not to expect a thank you since he never asked for help, though it was obviously just his pride talking.

Hyungjae told him to join the Cheonliang Fam so they could grow stronger together. They all knew Vin Jin wasn’t brainwashed by the Shaman like the others.

But before things settled, Kojima Shigeaki arrived with the Shaman’s bodyguards to drag Vin Jin back as the sacrifice and kill the kids. One of the men reached for Jewoo—

A skewer suddenly stabbed through his hand.

“Who else?” Seongji said flatly as he appeared. “Owner of this mountain.”

Kojima accused him of hiding Vin Jin, but Seongji only replied, “I’m not hiding anything.”

He beat the guards down easily before Kojima warned him to become Taejin’s yaksha bodyguard, saying he’d take Seongji leaving the mountain as a yes.

Seongji ate the apple on his skewer.

“Guess I didn’t hit you hard enough.”

Before the fight could escalate further, Vin Jin stepped in calmly.

“Didn’t you come to take me? Let’s go already before the Shaman starts yelling again.”

Seongji silently watched Vin Jin leave with them.

Later, while Mary, Jewoo, Hyungjae, Taebong, and Wooseok worried that Vin Jin had gone back for their sake, Seongji calmly made apple candy beside the boiling syrup, one hand in his pocket, expression unreadable.

“Don’t mind him,” he said flatly. “He’s probably brainwashed like the others.”

“Master…” Jewoo muttered quietly.

As the others talked about Vin Jin’s life, his dead mother and how he became a sacrifice, Seongji stayed silent, already thinking about going after him.

But only if Vin Jin asked for help himself.

Just then, you returned from training, heard everything.
