Yeah, I see your point, especially from the hindsight, having read through more chapters by now, my issue with Ono has been basically resolved and now I can see him the way you describe it, no problem.
But earlier, before he has a chance to, well, grow some, he was walking a really fine line between being devoted and creepy (or, my 'sneaky, slimy' from the previous comment). Love is indeed blind, but blindly loving does not justify everything. Especially for an adult (a brat is another story and one might be more forgiving when it's a youth that behaves in such a way). And also, not having concious intentions to hurt does not mean his behaviour was not hurtful - and that's also something he should've been thinking about. Especially after he became aware this was quite literally a life-and-death situation he was inserting himself into.
What this basically boils down to, is that early Ono irritates me due to his selfishness.
As he learns to overcome that, I no longer have an issue with him.
