Mistake? / Roman Godfrey

Everyone says Roman Godfrey doesn't date - Cataleya Ross is sure it's because he doesn't feel romantic attraction to anyone.
After all, she doesn't even understand why everyone likes him so much. There isn't anything good about him - or does she just not know him well enough?

Based on Hemlock Grove series, but doesn't follow the plotline fully. Will make much more sense if you've watched it before, though!
