Night x Riiko but... I don't really know how to use hidden spoiler tags and everything has been said so I'll leave it at that. Out of those two I like Night best, but my number one choice (as a favorite, not for Riiko) is Gaku.
Knight! He's soooo sweet and he really is the perfect boyfriend but he also has his flaws but his flaws just make him seem awesomer. I can't stand Soushi! I kinda hate guys with glasses it makes them look soooo dorky especially when its Soushi.
