I suddenly want to re-read a BL manga I read some time ago, but I can’t remember the name. It is about a dragon and a human. The human has a twin brother and is a royalty who usually ages very slowly, but was cursed to age quicker than his twin brother (but still slower than normal human). The dragon is obsessed with him. He goes to live with the dragon in the end.
I appreciate any help you can give.
Im pretty sure you meant this one
