The Other World: The Happy Life of the Yellow-Haired Tutor

Ah Bin's academic performance was not ideal.
Just as he was worrying about going to university, he suddenly received an acceptance letter from the other world.
Chen Bin's imagined otherworld: Snow Woman, Maple and Bell, Lady Mira, the defiled Akane...
The real-life underworld: Bai Jie, Zheng Yiyun, Liu Ruyu, Chen Xinran on her wedding night...
Although it's different from what I imagined, it doesn't seem bad, that's what Chen Bin thought.
But soon he received a commission from the system: to have a one-night stand with his classmate in the presence of others.
