The romance is so sudden, almost as sudden as the 'fuck buddies' switch that really got triggered out of friggin' nowhere. Worst downside is it's really rushed for it being presumably five chapters and we don't even have the other two chapters available after all these years. As such I can only give it an ok two stars in consideration of the fact that if you get excited for what comes next you'll be sorely disappointed.
