- I view Dongrang as a really fucked up clingy ex-boyfriend who yearns for the older days, someone who always views Yi Sang as more of an object than a person. He knows what Gubo did to him and does feel genuinely sympathetic, but it's moreso due to jealousy than an actual moral compass. He wishes Yi Sang would've followed him to K Corp, but instead Gubo just had to take him by the hand.

- Samjo is someone he really does care about deep down, but he also views him as a replacement for Yi Sang. He took a liking to Samjo because of his hair and eye color alongside his clear loyalty. Also because he's a swimmer and can suck dick without having to go up for air much. Eventually he got attached and doesn't know how to feel about it because he views Yi Sang as his soulmate, even if he doesn't care about him anymore.

- Yi Sang and Dongrang dated in the League. They had their first kiss in the barn with the calf. They had what seemed like a super happy relationship, but Dongrang had his unhinged moments that really made Yi Sang question him. Dongrang's odd behavior was something Yi Sang, who was inexperienced with romance, brushed off as "love". This is what led to him clinging to Gubo despite everything, even knowing he only cared about himself.

- The thing Dongrang wants most in a relationship is loyalty. The thing Yi Sang wants most is safety.

- Yi Sang does love Dongrang back... But he's certainly not sure how to feel about it, and it's probably not healthy.

- Dongrang has cold hands from poor circulation.

- Okay, LGBT headcanon time. Dongrang is a cis gay man. Yi Sang is transmasculine and unlabeled both in gender and sexuality.

- Mental health wise Yi Sang is autistic with CPTSD, BPD, and dissociation issues. Dongrang has extreme issues but refuses to get diagnosed. Just call him yandere.

- Funnily enough, Dongrang has a severe fear of abandonment, but he has no qualms with abandoning others himself. Obviously.

- Dongrang always wanted to start a family with Yi Sang. Yi Sang was never that into it.

- They were absolutely the most fucking annoying couple ever in the League. I'm talking THAT couple in high school, but two grown men. Their friends would've all celebrated when they broke up if 1. it wasn't because Dongrang sold them all out and 2. Yi Sang didn't leave with Gubo.

- Dongrang keeps the desk for Yi Sang in his lab clean every day, and he made it as soon as he moved in. The others think he's pretty obsessed, but the bonuses are good and Dongrang's supposed to be a genius, so...

- Dongrang pretty much had an emo phase because of Yi Sang in his hometown. Again, most annoying couple ever.

- If Dongrang won and Yi Sang became his new assistant, working alongside him at the desk he prepared, things would definitely get very very toxic. Yi Sang falls in love with him because he's all he has left, a lot like how he fell in love with Gubo. Yi Sang has everything; a loving boyfriend, a perfect job, a wonderful apartment in a Nest... But he still feels empty, because Dongrang only cares about himself. He truly becomes the 'taxidermied genius' he speaks of, completely lifeless and feeling empty with nothing but a strange sort of love for Dongrang. Dongrang loves him back way more, giving him sweets and spoiling him, but in the end he only truly cares about himself; and having something pretty who likes him, of course.

- I throw in Dongbaek often. I headcanon them as a gay trans man. I also like to throw in the rest of the League, especially Gubo.
