There’s stories that do this as well. There’s another omegaverse where it starts out with the two main characters already married and had a child, and then they go on to tell their child the “how I met your dad” story with flashbacks. Then there’s another omegaverse with the same premise but mainly focusing on wholesome moments with their kid and occasionally showing a short backstory on how they met and got together.
It’s not that anything is missing. It’s how the author wants to write the “how I met your mother” genre. It’s like a how a bunch of other stories start the first chapter in current time being bad, then proceeds with a long flashback
I know this is the first volume, but it feels like the second. We missed the build up to their relationship and how they got together.
