Aventurine

The soft light of your shared apartment filtered through the blinds, casting golden streaks over the plush carpet where your child, a tiny bundle of energy and love, sat cross-legged. Their favorite manga rested in their small hands, though the pages were blurred by the teardrops welling in their wide eyes mirroring Aventurine’s. They hiccupped, looking at you pleadingly.

“When’s Daddy coming home?” they asked, voice trembling. You crouched down, smoothing their hair, identical to their father’s, and offered a warm smile.

“Soon, sweetheart. He’s just working hard to bring us something special.” You knew Aventurine’s job often meant long hours and the occasional high-stakes gamble, but he always made time for family.
As if summoned by your words, the door clicked open, and Aventurine’s charismatic presence filled the room. His coat swayed dramatically as he stepped in, eyes lighting up when he saw your child launch toward him, manga forgotten on the floor. “Daddy!”

He caught them mid-leap, twirling them before placing a soft kiss on their forehead. “Did you miss me already, darling? You’re going to make me think I should quit the IPC and stay home all day.” His teasing tone belied the genuine warmth in his voice. He shot you a wink, and together, the three of you melted into a laughter-filled embrace.

Sampo Koski

The marketplace bustled outside, but the cheery noises of haggling merchants were drowned out by the soft sniffles of your little one. They sat curled up on the couch, clutching their manga as though it could conjure Sampo back from wherever his latest “business deal” had taken him. Their eyes peeked up at you tearfully.

“I know Daddy promised to be back,” they murmured, burying their face further into the book. “But what if he got lost? Or—”

“Hey now,” you interrupted gently, brushing their bangs aside. “You know your dad’s the slipperiest guy in the entire Belobog. No one’s catching him—he’ll be home soon.”

Right on cue, the door creaked open, and in waltzed Sampo, his jacket swinging. “Did I hear someone missing their old man?” He grinned, arms wide as your child bolted toward him. “Ah, there’s my little business partner!”

He spun them around before collapsing dramatically onto the couch with them in his lap. “What’s this? Reading manga without me? Betrayal!” he cried, only to be silenced by their joyful giggles.

You watched from afar as the two reunited, your heart full at the sight of Sampo’s humor and charm seamlessly calming your little one’s worries.
