You decide that even if Darien is flirting with Rai, you shouldn't flirt with the guy so you figurativly step back and let Mina and Lita flirt with him. You ask Ami if she will go to th emall with you explaining that you need some cheer-up-shopping-time. You guys bid good bye to the others and walk down town. You have an okay evening, you find a pair of really cool heels that are half off. But still, you're plans with Darien didn't exactly go as you hoped. But hey what's a girl to do?
This is one of the seven endings to the story. You didn't do too bad, but there are a couple of better endings. But believe me there are some that are way worse as well.
