Pairing #6 - Aizen and Gin
There was no shame for Aizen or Gin when the other captains found out, they frankly didn't care that others knew about their relationship.
Years after Gin grew old enough to be considered an adult, he and Aizen shared how much they felt and since then had a secret relation behind closed doors.
They weren't ashamed per say, they just didn't tell anyone besides Tosen who had walked in on them making out in Aizen's office.
It was a mystery how no one realized what they were doing, that is until jumped Aizen in the meeting room before everyone else showed up.
Both had to admit though, that the other captains expressions were priceless when they entered the room to see them making out on the floor.
Unfortunately they thought they killed one of the captains when a loud crash sounded, and jit turned out to be none other then Ukitake who fainted from shock.
Aizen was ready for any punishment but ended up gapping and wide-eyed as their relationship was accepted by the sou-taicho.
Most of the other captains congratulated them or just accepted, unfortunately the bad thing about them finding out was the teasing.
