I felt like I didn't breathe while reading the first chapter up to the last. But I like it (mostly the part when nii-chan's became the bottom). because it's kinda new to me since I'm not into dark bl manga but turns out it's still good and a happy ending... I guess?
But the real Han was ordered by the pharmaceutical to drink something since he's being experimented to be an omega? But it's not like, to seduce the prince ang have smex but to use his pheromones if it will take effect to him as a complete success omega. Haha someone please correct me ┗( T﹏T )┛
YO THIS IS NOT THE END, THERE ARE STILL SIDE STORIES
