Knowing how this story goes, he will probably encounter a legendary dragon that he will add to his harem party.
Also its kinda refreshing to see the whole egg hatching 'plot' not be dragged out and just resolved within seconds lmao. Instead of the potential drama that is ''The hatchling imprinted on him instead of the actual owner?!'' that I know some writers drool about writing.
I know its like 34 chapters in, but its also refeshing reading a MC that is level headed most of the time.
Now he just needs to start being active with his harem of dragons. Collette is clearly thirsty but is too tsundere to admit it!
