I've heard a few theories that Credence is actually Graves's illegitimate son and that's why he ended up getting close or why Grindelwald chose to exploit it. But anyway I want Original!Graves and Credence finding each other and having an intimate relationship but Graves figures out that Credence is actually his son. Maybe after living together and teaching Credence magic he learns Credence has this Innate Talent that's very rare and only members of the Graves family can do (like that necromancy thing that was awesome, or parseltongues, or lightning magic) or maybe Credence has a locket or something from his birth mother and Graves recognize it as a present he gave to her a long time ago.
What Graves does with that knowledge is up to you, but basically I want an established relationship with unintentional incest where they realize it too late.
