Your favourite samurai wants to invite you to a restaurant. Why? To eat some udon, of course! What did you expect, a romantic evening with wine and stuff?
This is your roommate. You and she have gotten along long enough to see many many of her hookups come and go. She smashes... a lot... but not you. (Yet?)
You has watched her tape. This means her goal is to kill you. She cannot leave until you are dead. This means that technically she does not HAVE to kill you.
