I Became a Kindergarten Teacher for Monster Babies!

Alina's steps slowed as she reached the entrance of the classroom again.

Her throat felt tight.

She had searched every corner of the garden, peeked into the clinic, and even checked behind the kindergarten, her worry growing with every passing minute.

Still no sign of him. Her legs throbbed from all the running, her eyes burned from holding back tears, and her chest felt unbearably heavy that tight, aching kind of weight that comes just before the dam breaks and everything spills out.

Maybe… maybe he wasn't here anymore.

She pushed open the classroom door gently.

The soft rustle of movement greeted her.

Sable was still looking, his little shadow body crouched behind the storybook shelf. His eyes widened the moment he saw her.

"Teacher?" he whispered, his voice soft and hopeful.

Felix turned around too. "Did you find him??" he asked quickly, his voice full of worry.

Lucien stood by the corner near.

Alina shook her head slowly, a quiet motion filled with uncertainty. Her lips trembled—just slightly.. like she was trying to hold back words that didn't know how to come out.

She stepped into the room and walked over to her desk, her steps a little slower than usual. Her fingers brushed the edge of the desk as if grounding herself, and she took a quiet breath, trying to keep her voice from shaking. "I… I didn't find him," she said softly. "I don't know where else to look… but we will find Boo..."

She tried to sound strong for them, but her voice cracked at the end. She turned away quickly, not wanting the children to see her face.

Her fingers reached for her bag with a quiet sigh, unzipping it to take a sip of water—maybe it would help her calm down.

But as her hand searched inside, her brow furrowed.

Her water bottle wasn't there.

"Huh…?" she murmured under her breath, a faint crease forming between her brows. Her fingers fumbled for a moment. She always kept it right in the front pocket.

Maybe she dropped it earlier?

She leaned down and looked under her desk and then froze.

Her breath caught in her throat.

There, nestled in the quiet shadow beneath the desk…

Was Boo.

His little body was curled up like a sleeping mist cloud, hugging her water bottle tightly with both arms.

His form was still semi-transparent, soft and misty, like a morning fog holding onto the floor. But even in that ghostly state, she could see his peaceful expression… the way his little cheek was pressed against the plastic of the bottle like it was something precious. His chest rose and fell with quiet, sleepy sighs.

Alina's heart clenched and then softened completely.

"Oh, Boo…" she whispered, her eyes instantly filling.

The tears that had been threatening all this time finally escaped, slipping down her cheeks as she crouched carefully beside him. Her hand moved forward, brushing back a little strand of misty hair from his face.

He looked so small under the desk. So fragile.

He had disappeared not because he wanted to be dramati but because he was hurt and needed comfort. And in the end… he had come right back to the one place he felt safest.

Her desk.

Boo stirred gently at her touch.

His silvery eyes blinked open—pure and shining like moonlight, soft lashes fluttering as his gaze slowly met hers.

And then—his whole face froze.

His eyes widened.

He immediately sat up a little straighter, still holding the water bottle, his glow flickering with panic.

"I—I didn't mean to hide here!" he whispered quickly, almost breathlessly. "I didn't want to make you mad teacher! I—I was going to come out, I just… I was scared…"

Alina reached out and gently cupped his soft, flickering cheek. "Shh… it's okay," she whispered.

But Boo's words rushed out again, "I know I shouldn't show tantrums—Council ghosts say it's selfish! I didn't mean to cry! I'm sorry, I'm sorry, teacher—don't hate me—!"

"Boo." Her voice was soft but firm as she leaned closer, brushing her thumb under his glowing eye. "I could never hate you."

His lips trembled.

She smiled gently, her tears still quietly falling. "You're allowed to cry. You're allowed to feel upset. You're allowed to want comfort… because you're just a child, sweetheart. And every child deserves to be loved. Even ghost babies."

Boo looked at her for a long second.

Then he burst into tears again—except this time, it wasn't sad.

It was relief.

He dropped the bottle and flew into her arms, wrapping his misty arms around her neck as tightly as he could.

She held him close, letting his little ghost tail swish gently behind him.

Alina slowly stood up, cradling Boo gently in her arms.

Her breath hitched for a second because something felt different.

He was solid again—no longer a flicker of mist or fading light.

His small arms had weight. His chest rose steadily against hers. His silver hair brushed her cheek like real strands. His cold little hands were clinging to her sleeves, trembling slightly… but real.

He had turned solid.

A soft smile bloomed on her face, despite the tears still fresh in her eyes.

"You're back," she whispered, holding him tighter for just a moment longer.

She lowered him into her chair, and helped him sit upright. He looked so tiny there, feet not even touching the ground, silver hair a little messy, but his glow calmer now—quiet like moonlight instead of stormy mist.

Alina crouched in front of him, brushing his hair behind his ear gently.

"Boo," she said softly, "do you drink water?"

He blinked up at her, surprised by the question. Then he gave a tiny nod.

"Y-yes… I can drink," he said quietly.

She smiled. "Alright then. Let's have a few sips, okay?"

He nodded again, shyly.

Boo could eat food. He could drink water. His body was strange, unlike other ghost but it worked. He could taste things, chew, swallow. Sometimes the food faded right through him if he wasn't focused, but if he concentrated, it stayed inside like it was supposed to.
