Watch Season 1 DC, then both OVA’s then normal watch order (Season 2 followed by Season 3).
Directors cut is worth watching over the non DC. I dont believe there’s another OVA besides Frozen Bonds but ive also not finished S3 yet I forgot there is a second OVA. You’d watch Memory Snow first followed by Frozen Bonds
