-When Iseul was young, he told the counselors at his school about his twin problem. This resulted in his being in a mental ward for kids and tested for schizophrenia. He also was suggested therapy but Rika said that he was just as normal as any other child. He believed her.

-When he was a child, Iseul would have nightmares. Rika would come in and comfort him; after all, that's her son.

-Rika knows when Iseul is possessed because the twin always talks about how V is doing in heaven. Rika is worried but doesn't know how she could possibly help her son.

-After everything, Areum is still in love with Iseul. Iseul is in love with her too but he keeps his distance. He knows he isn't the best option for her and tries to keep her away. Has even told her she should be afraid. Tried to make her fear him but can't if not possessed.

-The only person he's ever kissed was Areum.

-Both Iseul and his twin are in love with Areum. Whenever Areum tries to kiss him or anything, he tries to not let her. If she does kiss him, he will hear his twin repeat 'Mine' over and over in his head.

-When Iseul met the original RFA, they were all quiet because Iseul looked like a spitting image of V only with blonde hair. Jumin nearly cried.

-Iseul never likes it when others talk about V. Iseul either turns into a puddle of tears or turns into a violent satan, sometimes it's a mixture of both.

-Iseul started to hang out with Jisu but he knows there's really nothing they have in common.

-Iseul is as cheesy as Laon. His ideal date is near the ocean. On a beach or something.

-Jeaki and Iseul have thier moments. When Iseul smiles, Jeaki can't help but smile too because Iseul has such a cute smile. Jeaki loves when people have good smiles.

- When Iseul feels possession taking over, he will lock himself in his room. He will ignore Areum, Eunha or Laon knocking because he feels that's just his brain trying to trick him but when Gyeong, Jisu or Jeaki knocks, he's sure it's real because they aren't very close to him. He still will not open the door but will answer verbally. He's trying hard to keep control.

-Iseul has been in an actual relationship with Areum. Before he kidnapped her and everything else. It started because they went to the same college and talked more and more. Jaehee and Jumin did not meet that boyfriend she kept talking about.

-Iseul sometimes wakes up possessed. This is how his yandere self got to Areum. She had visited his home early to walk to class with him.

-Iseul's twin asked if he'd like to sell his soul to him. He refused.

-Iseul tried to kill himself to protect the RFA because he knew this demon he called a brother wouldn't leave him alone. It was when the RFA went to save Areum and he gained control for a moment.

-Iseul loves affection just like Laon. He loves hugs and kisses. He loves the feeling of kisses more for some reason.

- Iseul hates his appearance. Mostly because he believes he doesn't deserve the face of his father. His father was explained to be an angel and he believes he is far from that.

- Iseul tried to run away when he was young to protect his mother.

- Jisu has told him once before that she is in love with his eyes.

- Iseul would love to go off the grid for a week or so. Just stay in the woods with a cabin and just do everything himself.
