Late Night Alumni

There is a little part of me that wants the best for you.
Can't help but wish the best was me.
Coquette I bet you'd say I am, a vixen ripe for play.
You sound so sincere when you say,
I'm an open book, despite my puzzled look,
and coax me to confess to all I never meant.
This is the absolute last time you'll fall in love with me.
I nod my head like I agree.
If I'm a siren in the night you aim in vain to fight,
