- Dongrang is really into scientific scenarios that are almost medical. Post-League he likes to put on his K Corp uniform and do consensual "experiments" on Yi Sang.

- Even before moving to K Corp, Dongrang liked to give Yi Sang K Corp aphrodisiacs and truth tablets to see what would happen. Yi Sang was very into it, but lost that interest after Gubo.

- Dongrang is dominant usually (he hates giving up control) but when he's broken down, he's really broken down. I'm talking ass pounding life changing submissiveness here.

- Likewise, when Yi Sang is dominant, he's really dominant.

- Dongrang's biggest kink is aphrodisiacs. Yi Sang's is praise.

- In K Corp, Dongrang often has sex with Samjo while pretending he's Yi Sang. Samjo knows this and is just happy to have any of Mr. Dongrang's attention.

- Dongrang's neck is incredibly sensitive, and Yi Sang likes to bite and kiss at the mole there.

- Dongrang has a huge oral fixation and likes to put his fingers in Yi Sang's mouth and hand feed him.

- In bed, Dongrang is sickly sweet and likes to put all of his attention on Yi Sang. He loves him, after all.

- Yi Sang is extremely messy when he cums. This is canon to me.

- Dongrang is very possessive during sex. Possessive to the point of having a giant breeding kink since he wants to claim Yi Sang that bad. Yi Sang can't get pregnant though so it's fine.

- Whether or not Yi Sang has bottom surgery is 50/50 to me. Maybe he can just... go go gadget pussy??? Either way, he has a hysterectomy.

- Dongrang has a huge thing for implanting Yi Sang with strange unfertilized synthetic K Corp eggs. He's a freak and Yi Sang's in heat, it's a terrible combination.
