It's about girl that is accepted into some famous school ( i think stid I'm not sure) . And discovers that superpowers exists. And that her d.n.a. is like there's but she is different because she is a Zero ( has higher chance of having baby with O-s and can transfer ability to baby). So everyone wants to have sex with her and ther is this super famous teacher super sexy and all that. Her family is working at chicken shop and because of the danger they were brainwashed. She wants to see them and the teacher is taking her to them. I think teacher is called Ethan. She saw them and because it was dark and Ethan lost his power they had to stay at his house. They had sex and then he betrayed her ,sold to the another organization something on L and they were at organization M.
I know that some moowa saved her but lost his power and they teleported to some forest. They were ther for 5-6 days i think. When they finally got discovered they had filings for each other.
