Read the sypnosis first..
You (as MC) are a proffesor..
You need to prove your research to stop Epidemic that can kill every 19yo Girl and older..
Your research is not about alchemy / cure, its about mental / emotional..
In this case, you are therapist, not psychiatrist.. right ?
Why u need ask every 18yo problem, when you know that the only problem is they can be dead in next year ?
And for girls who has already 19, they can be death by the unknown epidemic anytime..
