I am guessing that this isn't the actual end… At the beginning of volume 3 the scanners mentioned that even they thought that volume 2 was the end - and then they came out with another one! ( http://www.mangago.me/read-manga/heart_no_diamond/mf/v03/c011/5/)
*spoilers ahead*
Honestly though, I hate all of the characters in this manga… I definitely like Himeno the best though. (Hey, it's not her fault that jerk published the book about her heart diamond and set every guy in the world after her, causing her to not trust anyone! And bullying is wrong no matter how popular her knights are!!!) (︶︿︶)
At first I liked Mamoru since he was saying he wanted to help Himeno find the guy who she would love from the bottom of her heart. But given what a jerk he's been about Keigo and the fact that he also won't admit his own feelings for Himeno… don't like him anymore… (Plus he'd rather Himeno be bullied than let any guys near her! What a jerk!) ┑(￣Д ￣)┍
With Keigo… I keep fluctuating… but the balance is definitely tipped towards the "hate" side because he's always such a jerk. It was also really stupid of him to go through with the Knight ceremony after not quite confessing to her, and not finding out her true feelings for him first. He just keeps ending up hurting her ever since. (Plus, seriously? He'll die if he falls in love with her? Yeah right; he'd be dead 20 times over by now if that was actually true!) (づ￣ ³￣)づ
Was that really the end? I don't get it? What about the whole death to the knight who loves the hearts diamond? What about Mamarou? I really don't feel an ending here? ヽ(`Д´)ﾉ
