Y/N sat on her bedroom floor, surrounded by a myriad of makeup products. She glanced at her brother, Malfoy, who was sitting reluctantly across from her.

"Malfoy, this will be fun. Trust me." Y/N reassured him, holding up a tube of mascara. Malfoy rolled his eyes but stayed put.

The first few attempts were disastrous, mascara smearing and eyeshadow dusting his cheeks. But Y/N was persistent.

"Why am I even doing this?" Malfoy groaned, as Y/N was applying some blush on his cheeks.

"Because it's fun and because I said so," Y/N replied, not taking her eyes off her task.

"You know I'm not a doll, right?" Malfoy remarked, trying to get out of the situation.

"Too late now," Y/N shot back, a grin on her face.

After an hour or so, Y/N finally stepped back, admiring her handiwork. "Not bad," she said, smiling.

Malfoy looked at himself in the mirror. His face was painted in soft hues of pink and gold, his eyes lined perfectly.

"You actually did a good job," he admitted, a hint of surprise in his voice.

Y/N beamed at him. "See, I told you it would be fun."

"Fun for you, maybe," Malfoy retorted, but his usual smirk was replaced with a soft smile.

"Alright, alright. Let's clean you up," Y/N said, grabbing a makeup removing wipe.

As she gently wiped off the makeup, Malfoy's eyes closed. Y/N noticed his features softening.

His usual stern expression was replaced with a rare, relaxed one. Y/N felt a sense of satisfaction.

"I can't believe I let you do this," Malfoy murmured, his eyes still closed.

"I'm glad you did," Y/N admitted, her voice soft.

Malfoy opened his eyes, looking at his sister. "Why?" he asked, genuinely curious.

Y/N shrugged. "I don't know, it's... different. It's fun."

Malfoy nodded, understanding. "Well, it wasn't as bad as I thought it would be."

Y/N laughed. "That's the spirit, Malfoy."

Their laughter echoed in the room, a rare moment of sibling bonding.

As the day turned into night, the siblings found themselves talking about everything and nothing.

Despite their differences, they found common ground. The makeup session turned into a bonding session.

Y/N and Malfoy learned more about each other, their likes, dislikes, fears, and dreams.

It was a small step, but a significant one towards a stronger bond.

A bond that was not just built on blood relation, but on understanding and acceptance.

"Maybe we should do this more often," Malfoy suggested, surprising Y/N.

Y/N smirked. "Are you saying you enjoyed getting your makeup done, Malfoy?"

"No," Malfoy quickly responded, "I'm saying I enjoyed spending time with you, sis."

Y/N's heart warmed at his words. "I did too, Malfoy. I did too."

And so, the day ended on a happy note. A day that started with makeup ended with smiles and laughter.

It was a day that brought them closer, a day that created a bond, a beauty bond.

It was a day they would remember, a day that marked the start of their newfound bond.

And as Y/N looked at her brother, she knew that this was just the beginning of their journey together.
