Smile Again - Bittersweet

So the story starts out with Aqua and Xion shopping. As you can see there is a time skip from Christmas to Valentine's. We have to remember this part of the story is all a memory to Xion. A huge flashback. Only certain things in her memory that stand out the most to her are recollected.

Aqua and Terra are something big because they are what got her started with involvement in Vanitas and Ven's life.

So by snooping around with Terra, Xion finds out Vanitas had set up Terra and Aqua. Of course this confuses Xion. He was the one who wanted Aqua to be with him. Vanitas tells Xion it's her Christmas gift. Something to show a 'nice' side to Vanitas.

Of course it's ruined when he says she basically has no chance with Ven. Jealousy? Hate towards Ven? Just being plain ol' Vanitas? Who is to say right now.

It puts Xion down but Ven comes in to save the day. He takes her out on a date! And right before they depart, Xion sees Vanitas. Xion I guess has sort of has a defiance stance with him at this point. She's thinking 'haha you were wrong.' In a sense she's still like a kid in wanting to prove others wrong and she hopes he is thinking that 'wow Xion was right and I was wrong.'

What he really thinks? Well that's saved for another time.

Music time!

Dreaming Island's Story by Yiruma

(sorry I couldn't find a better version)

When it's played: When Ven suggests to go on a date.

Reasoning: It has a gentle start. I can just imagine Xion being sad, and then when the song picks up in intro is when Ven suggests for a date. It gets a happier tone for when she smiles, but a sad tone when she sees Vanitas.
