Do you know the name of this yaoi ABO?

Hello! I just remeberd one ABO. Well, not really remembered, but the pregnant omega guy was in coma and dreamed about his grandpa I think? And there was a puppy? A child? I don't really know, but grandpa said that he should go back (to life) but he can't take it (the puppy/child) with him yet. And after waking up he discovered that he miscarried. I cant remember anything else tho.
