Why i love Shizune ...
She never lied / hid the truth to Hisao , she is blunt and doesn't tip toe around an issue , she is loyal to the ppl who are close to her ( Misha , Hiaso ) , she doesn't change who she is no matter how hard ppl try ( her dad , lilly , lilly fanboys

The downside of Shizune ...
She is a taskmaster and dosen't realize ppl can't work at her pace ( misha is really the only one who can ) , the way she make everything into a game
Why i dislike Lilly...
She hid the truth about Scotland ( Akira told Hisao ), She treats Hisao and Hanako like there are made of glass ( hanako grow more in lilly path then her own ... cause lilly wasn't there to mother her as much )
The upside of Lilly ...
She dose seem like the only one who can under stand Hanako
In the end hiding the truth about Scotland is what made me dislike Lilly ( maybe lilly fans can overlook that fact but i can't ) ... i mean in Hanako path she had no problem telling hisao about Scotland ... What changed in her own path ( if Akira didn't tell Hisao ... would have Hisao forund out ) hiding the truth about something as big as that dosen't bold well for there future
yes i know at times shizune is a bitch ... but as i said before ... i rather take the truthful bitch then the lying saint
Edited to fix spoilers ... my bad
