How to get her
Okay. This might get a little complicated. First you dye your hair platinum white, straighten it as needed and let it grow out to your shoulders. You should also cultivate a third eye. Then you get rid of Dimand. It doesn't much matter what you do with him (like, you could give him to ME as thanks for giving you advice on how to bag a certain green haired temptress *hint hint*) as long as she never sees him again. Lastly, you impersonate him for the rest of your life!

Competition
I trust you can figure this out yourself.

She likes you if...
She blushes and hides behind her fan when you talk to her.
