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

You had been living with Seongji Yuk since the start of your training. Unlike his other students, you stayed with him not because you lacked a home, but because yours was in Seoul—far from Cheonliang. His small tin house on the mountain became your home.

Seongji Yuk loved you quietly, though he hid it well. He believed he was unworthy, that his love would only ruin your life. More than that, he was your mentor—only two years older, yet always insisting only you call him Ahjusshi, even if he secretly disliked it. While his other students called him Teacher.

At Cheongliang mountain near Seongji Yuk small tin house as Seongji Yuk sat on the ground arranging the woods he chopped for tonight's special meat dinner.

Vin Jin after losing to Mary again after calling her Elephant only to get slammed on ground by her Vin Jin kept his eyes on Seongji Yuk, who arranged the woods in silence. “Show me some finishing moves Teacher.”

Seongji Yuk finally looked up. “Go bring the clean stone to fry meat on.”

Vin Jin frowned. “Why would I?”

“You’re my student now, aren’t you?” Seongji replied flatly.

“I’m your student, not your servant! And where did you even brought meat from?”

“I hunted it.” Seongji Yuk replied dryly.

You returned after completing your course of training by Seongji Yuk being his first student as Vin Jin, Mary, Jewoo, Hyungjae, Taebong, and Wooseok immediately approached you as Sujin cheerfully hugged you ''I want to eat Yeonha-oppa cooking!"
