Oomiyabi

Kagura Rio is a perfect, cool, and beautiful girl who captivates everyone's attention the moment she appears in the classroom. She's academically brilliant, athletically gifted, and a total beauty. However, only I, Yonemine Sumito, who sits next to her and is secretly a telepath, know the truth. "Even though she's being played with by multiple people, her body can't resist...it feels so good." I know that what she's reading at her desk is an erotic novel (a pretty extreme one)! And during math class, she has the worst kind of thought: "That teacher looks like he'd be the top..." And during physical education class, she thinks of the girls, "They have big boobs. I want to grab them from behind." Kagura's mind is always far too lewd! She doesn't get close to anyone, but for some reason, she opens up to me and tries to get closer to me!?

"If you were to disappear... I might just lose myself." Arcs is reborn into the world of the wildly popular otome game Celestia Kingdom.

Determined to avoid the bad ending, he throws himself into his daily life as her servant. But it seems the true cause of her descent into darkness is... her childhood friend!?
