This was wonderful, I loved it. If you're confused about the timeline it goes Shige x Yuki (plus baby Haru) ch. 1-3, flashback of Yuki x Okaken (not the same person as Okamoto, Okaken has short blonde hair and Okamoto has long blonde hair) before Shige ch. 4, how Yuki and Okamoto met ch. 5, and then Shio x Okamoto ch. 6-7.
