Inconstant Z

Synopsis
We all want to live a normal and happy life. To graduate and have a decent job but what if on your school days you got involved into a secret group inside the school and the number one rule is to be a guardian of a guy. Not just a guy, let's say who only has a very rare condition and might change that normal life of yours. That happened to a girl named Ava and the rest of the students who also got involved inside the King's University.
