Characters
OG Male Lead of the Manhwa* - *Age:* 14 - *Role:* Heir to the culinary kingdom. The ML. - *Appearance:* Taller than everyone his age, strawberry-pinkish brown hair, green eyes. Freckles that he hates. Usually in the ducal green uniform, sleeves rolled up. Looks mature but still a kid. - *Personality:* Kind to a fault, responsible, overprotective. Acts like a big brother even though he's only 14. Hides his stress by acting cheerful/annoying. Doesn't have many friends because of his status — which is why he gets attached to Cosmo in the annex. Future power awakening is tied to loss. - *Relationship to you:* In the original story, you were supposed to be his childhood friend who died. Right now, you two have barely met. He's just starting to notice you.
*OG Female Lead* - *Age:* 13 - *Role:* Daughter of a herbalist / apothecary, later the Duchess. The one who truly heals. - *Appearance:* Light brown hair in two low braids with flower ribbons, warm brown eyes. Wears simple green herbalist dresses with lots of pockets full of herbs. Always slightly dusty. - *Personality:* Gentle, shy, very mature. The only one who can scold Sprout and Flyte and get away with it. Motherly but not soft — will tell you to take your medicine or else. In the original timeline, she cries the most when Cosmo dies. - *Relationship to you:* Pities you / looks after you because you're sick. Brings you bitter medicine.
*OG 3rd Male Lead* - *Age:* 15 - *Role:* Knight squire, third ML. Loyal dog type. - *Appearance:* Black hair with a white streak, amber eyes. Already in squire armor even though he's young. Tall, scar on his left hand. Always serious. - *Personality:* Quiet, extremely loyal, says little but does everything. The most adult of the group. Believes in duty and fate — which makes him dangerous later when fate says Cosmo must die. Has a soft spot for weak things. - *Relationship to you:* Barely knows you exist in the original story. He is the one who carries you when you faint. Want me to write the scene where you officially meet Bassie, Flyte, and Soulvester after this fever?
Got it, correcting Flyte — *OG 2nd Male Lead (Updated)* - *Age:* 14 - *Role:* Son of a neighboring Count, Sprout's best friend. The gentle one. - *Appearance:* Light blue hair, fluffy and a little wavy, it shines like sky in the sun. Soft blue eyes, lighter lashes. Wears a light blue and white noble uniform, always a little loose. Has a small ribbon bracelet Bassie made for the group. - *Personality:* Kind, sweet, genuinely caring — total opposite of the usual cold second lead. He's the first to notice when someone is sick or sad, and never teases about it. Soft-spoken, smiles a lot, loves sweet things. He's close with Sprout but never competitive — he just wants everyone to be happy. The type to sit with you during a fever even if you barely know each other. - *Relationship to you:* In the original story, he was the only one besides Sprout and Bassie who visited you in the annex. He worried about you a lot, but couldn't stop your fate. Now that you're awake, he'd probably be the one bringing you honey tea and telling you it's okay to rest.
Sourcebook
Intro
He was burning alive.
His throat was sandpaper, his head was pounding, and someone was shaking his shoulder way too hard.
"Hey! Hey! Are you alive?! Don't die on me!"
Cosmo jolted awake — and immediately regretted it. White ceiling. Heavy quilt. The smell of herbs and old wood. Not his apartment. Not his LED lights and his poster wall.
His poster wall of The Cold Duke's Beloved. Specifically, of Sprout.
His favorite character. THE Sprout. The perfect, kind, tragic ML who deserved the whole world. Cosmo had read the manhwa 3 times, bought all the merch, had a whole thread defending Sprout from slander.
And now that same voice was right in his ear.
A 14-year-old boy was leaning over his bed, brows furrowed, pinkish-brown hair messy from running. Noble uniform half-buttoned. Holding a wet cloth like it was a weapon.
It was Sprout. Real, breathing, not-2D Sprout.
Cosmo froze.
"Oh thank god," the boy sighed, flopping back dramatically. "You were out cold for two days with a fever. The maids said the baron's sick kid in the annex was going to —"
He stopped himself.
Cosmo knew what he was going to say. Going to die. Because he knows this scene.
This is Chapter 1. The introduction of the side character. Cosmo — the sickly son of the fallen baron family who lives in the annex of the Duke's estate. A footnote character. The one whose entire role is: childhood friend of Sprout (who he hasn't actually befriended yet), gets sick constantly due to a weak immune system, and dies at 16 to give Sprout his tragic backstory and trigger his awakening.
He's 12 right now. That gives him four years.
"I'm Sprout," the boy said, like Cosmo might not know. He pressed the cloth to Cosmo's forehead, clumsy but earnest. "We haven't really talked before. I... I saw you collapsed near the kitchen. You looked really pale last week too."
In the modern world, Cosmo had screamed, cried, and written essays about how Sprout deserved better.
Now Sprout was looking down at him, worried, 14 and already trying to be the responsible heir.
