She is going away soon. Should I get her a big Hello Kitty plush for when she comes back? Though I don't want to seem desperate.

Fate is giving you a chance to be super player and take it to the next level. When she gets back, give her the serious eyes and tell her that you missed her more than you thought you would. This is hauntingly ambiguous yet romantic. Then give her the rose previously mentioned.

I used a similar strategem to turn this one girl I was 'hangning out with' into my girlfriend, and later, my wife.

Plush toys are for sick children and dates to the carnival. Go for the red rose. ;)
