Don't cry baby - 18

It's slow update.. yeah, because I realized there might be something wrong with the plot. Shizuru is 18 years old in the profile right? And I don't sure if whether she has been 18 years old already or she will turn 18 in December (right now the story is in July). I graduated high school before my 18th birthday '__' , and the way people calculate one's age confuse me!
If she really isn't old enough to adopt legally, I will have the other way to go on with the plot.
