I've been looking for this fic for a while now, I would really appreciate it if someone could help me find it.

It's cas/dean with side pairings including Adam/Michael and Charlie/Anna.

John Winchester tries to sell Dean to the angels, the angels accept Dean but do not pay John as he's abusive.

Dean is then paired with Castiel as his mate.

Dean cannot live with Castiel until he is 18 so he lives with the other human mates in a centre of sorts.

Angels have control over their human mates and Castiel is able to dictate Dean's diet and bedtime inside the centre.

Castiel, though not an archangel, is considered to be the level of one. Therefore, Dean bunks with Adam and they have to use a private Golden Elevator.

Please help me find this fic.

Thanks,
