If you like ABO dynamics then I don't think you'll find much fault with this. It starts off a bit rough, maybe a little over the top and a little less mature, but once Derek and Stiles connect and come to an understanding, things fall neatly into place. I felt this was like an overall montage of the big moments in their life together - starting with how they met, then fell in love, and ultimately became a family. So in between a ton of cuddles, there's the typical possessiveness/claiming of heat cycles, KNOTTING, and mpreg. Simple, with a dash of heat and plenty of fluff.
