maybe i severely lack media literacy because ive read this twice and i still dont understand chang's obsession with ed...
other than that this story is so good
basically hes fucked in the head lol. ed wanted to be changs family and acted like changs dead little brother in a way, chang somewhere along the line fell in love with ed because of that (you can see this at the scene in the past where young ed is not wearing clothes and chang hugs him and they smt about being hot). When ed got into an accident, chang became scared of losing ed and wanted like some leverage over him even if it meant hurting him. Which ended in disaster ofc. You can see in their last interaction when he say ed as the younger version, he was obsessed because he couldn't let go of what they sued to have. At least thats what i think~
skipped to the end because i thought omg at LEAST the author would give him a happy ending after making him endure all that!! nope!!! so fucked up i hate this author and this story
