My Teammate Might Be Seriously Ill!

Different world background, DIY world. The story takes place 700 years after the rise of mankind~ Tina, who just wanted to prove herself, got a teammate from the mental hospital under the introduction of her half-cousin, and the two started cheating each other from then on. Tina: "You are sick, you are definitely seriously ill. You have a strange brain. I am a girl, so you can't let me do it?" Qiye: "So this is the reason why you whip yourself with a whip?" In short, this is a not-so-rigorous novel with a different world and western fantasy background. Perhaps? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
