MTL - My Backyard is the Tang Dynasty - ~ explain!

“Why? Just why?”“Why did I became this guy?” That was the first thing I said when I see myself on the mirrors reflection.Lucien Drelmont.A bottom-tier instructor at Noctis Ardentis Academy. A joke of a character. A corrupt, talentless noble despised by both students and faculty.He was one of the early game villain, that was destined to die, a stepping stone for the protagonist, a scapegoat for the Academy, no matter what way the game is played his death was destined.And now I need to survive as him, in this hellish academy._____________________[No Harem][No Romance][No NTR&Yuri]

Ryu Han-bin, the main character who fell into a new world after being chosen as a ‘suitable person’.

“Aria,” he said softly. “Today is your birthday.”It wasn't a question, but I nodded nevertheless.“The moon is full tonight,” he added, his voice quiet. “You will attend the ceremony.”“Of course, Elder,” I replied, puzzled. All eighteen-year-olds attended the ceremony. It was essential.He leaned in, smelling gently. “You already feel it, don't you? ”The change.My heartbeat skipped. “What change?”Elder Malin's eyes narrowed.

Inside was a simple moonstone pendant with a leather cord.“But this is for—”“Wear it,” he interjected. “Hide it under your clothes if you must, but wear it.”Moonstones were precious. They aided our connection to the Moon Goddess during ceremonies. However, they were only given to wolves from influential families (Alphas and Betas).

And tonight, those secrets may be revealed.”I never mattered in our pack. Omegas like me serve, submit, and survive. We don't dream of love. We don't dream of power.She was the future Luna. I was just the girl who watched from the shadows.But everything changed on my 18th birthday.I felt the bond. I met my mate.One of the Alpha's sons.But the Alpha has triplets, and I felt the mate bond with all three and it seems the three of them felt it too — three perfect warriors, three powerful Alphas, three secrets buried beneath the surface.One of them is my destiny.One of them is lying.And one of them might be the death of me.The Moon Goddess doesn't make mistakes... but this time, I think she might've given me too much to handle.

At the end of the story, I found myself in the body of a hidden villain, betraying the heroines. Since I’m not particularly concerned about the end of the world, I’m calmly waiting for the finale… “You’re the only one who truly appreciated my painting of the boa.” “When I make plans to meet you at four, my heart starts racing at three... is this what they call being tamed?” For some reason, the heroines are starting to take an interest in me.
