My oh my, haru... You feel guilty for what you have done, but you cannot get the forgiveness from run you are looking for. I take no pleasure in reading rape, this one simply invokes a feeling of greif and pity for rin. What I'm trying to say is that to think a book is good or not you don't have to like the actions the of characters. Haru did something unforgivable. And we can hate haru for this. Look at rin, don't you feel pity? Sadness for him? Some people cannot wrap their heads around the concept of feeling for a character that makes books good. Think about manga and books you've read. You've felt things for the characters.
You can hate this manga all you want, but please understand this concept.
