-Why did Tou have to leave his parents? Did they die?
-What happened to the main cat’s parents? They were only in the storyline through the memories of the doctor... did they die?
-Why did they decide to give up their children, if they didn’t want to? When did they make that commitment?
No they didn't die. Rin will give birth again after those six kids so ofc coz of society he have to gave his 6 kids to others in order to protect them and give them education. After they grow up like tou younger brother who he had slap and got injured in head... they have to comeback to look after their younger siblings. Rin parents is both omega and male. Tou younger brother an alpha is the next doctor *successor of ise* and tou will gave birth. So that's it. Cats tribe are treated like a gem in their society that's why.
WHAT THE HELL KINDA ENDING WAS THAT
