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. While Vin Jin, Sujin, Mary, Jewoo, Hyungjae, Taebong and Wooseok bickered teasing Vin Jin as Mary beat them all up except Sujin.

As Seongji Yuk was seeing those stares of other people again when he was a sacrifice to Shaman as his PTSD triggered as Seongji Yuk stood up making other stiffen thinking they are gonna get beat up again but Seongji Yuk spoke calmly ''You all go train on the training spot, Yeoha will probably be there as well and he will help you train.''

They all left confused as Seonji Yuk entered his house shutting the door as he leaned on his for spot sweating heavily as he covered his face with his hands while the memories flooded back. As then his uncontrollable seizures triggered violent rampages as he destroys everything around him.

Just then you returned from training to make lunch, you didn't see the other students on the way as you took different route as you entered the house.
