Its faster to just look through the tags lol I hope you find it though!
YES! Thank you so much!
Enjoy
there was a comic i read a couple years ago and i am not sure if i finished reading it, but i can't remember the name. it was korean and it had to do with a king and a dragon (king being the uke). the dragon guy always loved him and i remember there being a part that the dragon says that he doesn't age after 20, but he will alter his appearance to match the king's (the uke), and when the king dies, basically he will die too.
if you know what comic this is, i would greatly appreciate it!
