It makes it easier to start dating guys, and also to successfully date them and achieve their "Good endings".
There's no noticeable change to gameplay itself. It just means you have more room for error while you're pursuing a specific guy.
Oh and is it possible to have Nikhil's ending? Oh and for Jake part, are there suppose to have like sex scene or something like that? Sorry if I asked too many question but last 1 for now. What is the Parting Way thing?
