you're wrong im not aiming for "that" , they are many other DC guys who know about her BO past , and they have the perfect age for haibara .
Uhh... excluding (active and former) BO members the only other guys who know her past would be Heiji (who knows almost nothing about her except she is "That girl who played Conan during the Desperate Revival Arc"), Yusako Kudo (err...), Professor Agasa (...), maybe Kaito Kid (Did they ever meet?) and... well.... these are all.
And if we exclude Gin and all the other active BO members the only person that MIGHT be reasonable is Akai. I guess Akai has some idea of her true identity and knows her a bit through what Akemi told him. But since he feels responsible for her sisters death - and since he had never direct contact with Sherry and avoided her since she became Ai - this pairing is highly hypothetical.
So setting the condition that her future love has to know about her past and the BO is way too restrictive. And as I said, I have the impression that Ai prefers to forget about the BO and her involement in it.
Critical point: Miyano Shiho is nowhere near "very young"
True. But Ai Haibara is nowhere near "adult" as well. She will always have the conflict between her psychical and physical age. There are 3 ways to stop this conflict:
1) take a permanent antidote - thus becomeing Miyano Shino again
2) accept her new live as the truth - thus becoming Ai Haibara forever
3) continue the conflict for many decades - when the difference between her physical and psychical age doesn't matter
Of course an Ai x Mitsuhiko pairing will only work with the 2nd choise.
They know her assumed personality quite well. They know nothing about what she's really like. They don't know, for example, about the two times she took glee in scaring the living daylights out of Conan by convincing him that she was with the organization. They only know about her what she wants them to know about her.
I disagree. Of course she doesn't tell them everything. If it is because she doesn't want to get them involved with the BO, wants to get over her past with the BO or doesn't want them to pity her doesn't matter.
But just like Conan - who (at least in the past) was much more his true self in front of the kids then in front of Ran where he had to be careful all of the time - Haibara shows the kids her true character from time to time. They know about her hidden gentleness (especially towards animals) and they have seen her make sarcastic remarks about Conan or adults. They know she hiddes her true feelings sometimes which is why they drag her along often (And even though they are often wrong what Haibara really likes they sometimes find something to make her happy/cheer her up.)
And I can't imagine that Ai would want a boyfriend - or anyone - who could read all of her feelings and hidden thoughts. Except for her sister (which she didn't see often) of course. Quite the opposite, I think she would prefer something who knows when to stop snooping around in her buisness (or when she tells him to stop). Mitsuko does that.
