Here’s a few bits and pieces I remember about it:
-Poor Uke, Rich Seme
-Uke becomes confined to the Seme’s Hotel/Penthouse
-Uke is obsessed with survival shows
-Uke runs away and survives in the woods for a long time.
-Seme cries and apologizes when he finally finds the Uke.
I know it’s not a lot T_T Possibly omegaverse as well since I think the seme confined uke for a reason. Maybe a one-sided bonding or pregnancy.
