So for those confused as to why Hyesung stayed; No, it's not because of Byul, hyesung/bottom stayed. Cuz if u payed attention to the previous chapters, Hyesung/the bottom was planing on leaving even after Byul was born. It's because of their bond that he stayed, cuz Dojin and Hyesung would literlly die if being seperated 💀 How tragic tbh, since theres not much to these two except the dirty/smexif u know what I mean :/
