Ilyria Lillie Arzel has three marks and she couldn't tell anyone about it since she doesn't want to get involved, in marrying someone just because of the marks she has.

Unfortunately, Ilyria's secret is discovered by Aziel Marcellus, a popular boy at Nefelibata University. Instead of exposing it to the school, though, Aziel keeps it for himself and takes a liking to Ilyria because he finds her 'interesting'. But Illyria didn't know that Aziel also has a secret, that hasn't been known to other students.
