Some personal headcanons (Part 1?):
Whenever Cale gets a cold, he immediately starts bleeding like a faucet since the Vitality of the Heart is working to get rid of disease. Meanwhile, everyone thinks that this dude is so weak he sneezes and starts bleeding.
Lord Sherrit is literally a mythical/fairytale bedtime story for dragons in their world. A cool af dragon lord the likes of which has never been seen for 10,000 years? Baby Eruhaben definitely went around pretending to be the next Dragon Lord/daydreaming of meeting Lord Sherrit.
Choi Jung Soo is 100% the reason why Kim Rok Soo began working out and knows how to use different weapons. The two rookies would be seen in early mornings with Choi Jung Soo snapping at Kim Rok Soo like a drill sergeant.
On and Hong remain in their cat forms the majority of the time because they're light enough to be carried by their family members especially Cale. They like being close to their adults, after being rejected and neglected for so long.
Choi Jung Gun helped write some of the storybooks Lord Sherrit put in the Castle of Light for her children. Some of them were stories from the fantasy world, but majority of them were fairytales like Little Red Riding Hood and The Tale of Shim Chŏng.
After the Alberu PJs fiasco, his family keeps giving him fancy pajamas with increasingly absurd enchantments on them in case he has to head to battle again. Think baby pink pajamas with little cats on them charmed to protect against a literal Dragon's Rage.
After his mother's passing, Beacrox learns how to cook as a healthy coping mechanism for his anger and resentment. He is hesitant to tell Ron when he develops a genuine love for cooking, but Ron is supportive because he wants his son to not be tied down by revenge like he is.
As thanks for Choi Han's sacrifice during the Sealed God Test ("I can't even feed you properly here."), Cale quietly makes green onion pancakes for Choi Han. The swordsman tears up on his first bite because of the familiar taste but refuses to cry.
The first time Raon sleeps in Cale's bed is after a nightmare. It's before he gets his name and he is still guarded around humans. Cale notices him whimper, carries him in his arms and soothes the baby dragon each time. They never address it in the morning. After one point, Raon never leaves.
Choi Han has a diary he writes in so that he can never forget his beloved family members again, no matter how much time passes. He puts in every doodle or drawing the children make for him.
After meeting Raon, Eruhaben secretly begins preparing his lair for the baby dragon after his death as a gift. However, all his preparations get destroyed by the White Star.
The first thing Raon learned how to write was Cale's name, back when he was learning from Rosalyn.
The reason Cale's hair is so long is because he is too lazy (read: busy) to cut it. He has so many split ends that it gives Eruhaben a heart attack. Cale has a bigger heart attack when he finds out Ron is going to be the one give him a hair cut.
Alberu always, always carries a white handkerchief with cookies wrapped inside with him wherever he goes. His study and his bedroom are always stocked too: both for the children and for his dongsaeng who never eats enough.
Hong has a habit of rolling around in bed seeking warmth. At one point, he rolls on top of Cale's face, choking the man awake with a mouthful of fur.
Lee Soo Hyuk and Choi Jung Soo would talk about farming so often that at one point, Kim Rok Soo secretly went out and gathered a lot of farming/gardening books. He would record them all secretly.
Cale takes special care of recording each and every moment with his family. Raon's giggling when he wipes off the steak sauce on his face, On's quiet purring cuddled in his arms, the sunlight on Eruhaben's hair as he sits and reads etc.
The God of Death definitely giggled at being the first person to read Choi Jung Gun pen name Nelan Barrow's debut novel, The Birth of A Hero. He rated it five stars ofc, Choi Jung Gun held a broom to his head.
