I think Jin is a clone, but Setona isn't. Setona made a clone because his lover's dead. The clone turned out to be different from the real Jin so Setona was mad and drowned himself, but he didn't die. He was unconscious and lost his memory. Then the clone took him to the laboratory and made it looks like Setona was a clone to hurt him because he wanted to make him feel the same way he felt when Setona made him but didn't love him. At the end the clone wanted to drown himself because he didn't feel like he belonged there and Setona stopped him because he was finally able to love the clone and not the dead Jin. That's what I understand tho so I may be wrong.

That is also what I got too from the story.
About the abuse part, some couple likes it rough, you know? I don’t know if it is still consider abuse when one consented to it, but it seemed like Setona like it rough in bed but the clone Jin is too soft and that doesn’t resemble his late lover: original Jin.

Two consenting adults having rough sex is very different then what happened to the clone after he woke up. That was rape, there was no consent he even said he didn't want to and lamented the fact that he didn't even know his rapists name. I don't have a problem with people having kinks, hell I read yaoi but that was rape not rough sex.
Yaoi I love you but sometime...seriously what the fuck was that last story? A doctor made a clone for a clone? So that the clone could rape and abuse the other clone because the original person died? What the fuck was that last story? I'm confused on what was actually going on and also a person that falls "in love" with their abuser is not in love they're an abuse victim, how was I supposed to find that romantic? You wake up and are given to a stranger who, not bothering to introduce themself, drags you home and promptly rapes you. Also how do you rape someone who looks exactly like a person you "claimed" to love you sick fuck? Jesus Christ that was disturbing!!!!!! What happened to the original story? Yaoi seriously if you start out with a cute and fluffy story can we NOT jump into 50 Shades of sexual and emotional abuse please?
