Sun sat on his bed, clutching his blanket tightly. His wide eyes were fixed on the dark, ominous closet door across his room. He was certain that a monster lurked within.

The faintest creaking sound made Sun's heart pound in his chest. He was too scared to move, too scared to even breathe. He wished Moon was here.

Suddenly, Moon walked into the room, a smirk on his face. He could see the terror in Sun's eyes and couldn't help but chuckle.

"Still scared of the closet monster, Sun?" Moon teased, trying to lighten the mood. Sun just nodded, his eyes still glued to the closet.

Moon rolled his eyes, "You know there's no such thing as monsters, right?" However, his words did little to soothe Sun's fears.

As the night grew darker, Sun's fear seemed to grow. He was trembling, trying to hide behind his blanket.

Moon sighed, "Fine, I'll show you that there's nothing inside the closet," he said, walking towards the closet.

He opened the closet door wide, showing Sun the empty space. "See? No monsters," Moon declared confidently.

Sun peeked from behind his blanket. The closet was indeed empty. His heart started to calm down as he realized there were no monsters.

"You're just imagining things, Sun," Moon said, giving his little brother a reassuring pat on the back.

Sun nodded, finally regaining his courage. He was still a little scared, but he felt safer now that Moon was there.

"Promise me you'll stop worrying about monsters?" Moon asked, to which Sun nodded, hugging his teddy bear.

Moon left the room, but not before turning on Sun's nightlight. The soft glow filled the room, driving away the darkness.

Sun looked at the closet one last time. It wasn't as scary as before. He took a deep breath and crawled under his blanket.

He closed his eyes, hugging his teddy bear close. He felt safe, knowing that his big brother was just in the next room.

As he drifted off to sleep, he felt a sense of calm wash over him. The monster in his closet was no longer a threat.

With Moon's reassurance, Sun slept peacefully. He knew that there were no monsters, and he was safe in his bed.

The next morning, Sun woke up feeling refreshed. He looked at the closet, now just an ordinary piece of furniture in his room.

He smiled, realizing that he had overcome his fear. He was proud of himself, and he couldn't wait to tell Moon about it.

When Moon saw Sun's happy face, he knew that his little brother had finally conquered his fear. "No more monsters, right?" he asked.

"No more monsters," Sun replied, grinning widely. He was no longer the scared little boy from the night before.

Moon smiled back at his brother. He was proud of Sun for facing his fears. "That's my brave little brother," he said.

From that day on, Sun was no longer afraid of the dark or of monsters. He had his brave brother Moon to thank for that.

Moon had taught him that fears can be overcome, that monsters are only as real as you make them. He was grateful for his brother's help.

And so, Sun learned a valuable lesson. With courage and determination, you can face your fears and overcome them. And with a brave brother like Moon, he knew he could face anything.
