I actually read vols 1, 3-6 (2 was out). I found out about his father (if that is what you mean) and trying to kill himself and Isuzu, but the thing is, I am still not warmed up to him, even after 6 volumes. I just...I don't know. He doesn't work for me (not because he's unrealistic, but he just doesn't grab me). And the heroine is a bit too nice. I'd have broken his head :)
