Soul Fusion, I became Su Mu!

BAM!

A loud knock shook the door, followed by a panicked voice:

"Miss Su Mu! Are you awake!?"

Su Yang jumped, startled. Her heart pounded in her chest again.

"Su Mu?" she whispered. "Is… is that me now?"

As soon as she heard that name, a sharp pain spiked through her head. She staggered backward, clutching her temples. 

Images and thoughts poured into her mind—memories that weren't hers.

A girl's laughter. A ballroom. An ornate family crest. A sword dance. Quiet nights studying medicine. A name whispered in her ear: Su Mu.

The memories didn't feel like dreams. They felt like her life now.

"I… I really became her?" she whispered, stunned. "These are her memories. Her body. Her name."

The world spun around her as she tried to steady herself.

"I'm Su Yang… no… I was Su Yang. Now… I'm Su Mu?"

Her mind raced, trying to piece it together. Somehow, her soul had entered this girl's body. A new world, a new life. Even the surname matched, but everything else was different.

And the person outside the door—whatever she was—clearly knew this body.

Su Yang—no, Su Mu now—realized she had to play along until she understood what was going on. She had to keep her past life a secret. At least for now.

She sat up straighter and tried to calm her nerves, pushing her messy hair behind her ears.

Then the door burst open.

A girl entered in a hurry. She looked to be in her early twenties, with long blue hair tied back in a ponytail. 

Her clothes were simple but well-fitted—a dark blouse tucked into a neat skirt, with an apron around her waist. 

She was pretty, in a down-to-earth way, and her eyes sparkled with warmth and concern.

"Miss, are you alright!?" she asked, rushing to Su Mu's side. "I heard a shout and came running. You've been sleeping for days, I was so worried!"

Su Mu blinked, caught off guard. The girl's presence felt comforting, like a long-time friend or caretaker.

"I… I'm okay, I think," Su Mu replied softly, her voice still unfamiliar to her ears.

The maid, because that's clearly what she was, let out a relieved sigh. "Thank goodness. You gave me such a scare, Miss Su Mu. Are you feeling dizzy? Do you need water?"

The sudden shout from Su Mu's room had prompted her to hurry back after breakfast, her role as a lady's maid ingrained in her since childhood.

Growing up as a close companion to Su Mu, she felt a deep sense of responsibility and care for her well-being.

"I just… had a really strange dream," Su Mu said, choosing her words carefully. "My head still feels a little foggy."

The maid smiled gently and took her hand. "That's understandable. You've been through a lot lately."

Su Mu nodded slowly, not sure what exactly the maid meant, but too afraid to ask. She didn't want to raise suspicion. Not yet.

"It's rather unusual for the daughter of an Earl's house to shout like that," Meiling said gently, raising an eyebrow as she brushed a strand of blue hair behind her ear.

Normally, such a remark might be seen as disrespectful, but Su Mu could sense the easy closeness between them. 

The way Meiling looked at her wasn't just as a servant, it was as someone who truly cared.

Su Mu blinked, then a mischievous glint sparked in her emerald eyes. 

"Oh? And who was the one screaming like a banshee in the garden over a spider the size of a coin?" she teased, folding her arms with a smirk.

Meiling's face turned beet red in an instant. "Th-that was one time! And it was huge! And it moved!" she protested, flailing her hands in flustered defense.

"Awawa—!" she added with a series of unintelligible squeaks, her embarrassment plain as day.

Su Mu laughed, a soft, clear laugh that even surprised her a little. 

It wasn't the laugh she remembered from her old life, but it felt… warm. Natural. Real. 

She tilted her head, watching Meiling with amusement and a strange sense of affection.

She's so cute like this.

Something stirred in her heart. So this is what it feels like to be on this side of things…

A stray thought crossed her mind, both surprising and oddly thrilling. 

I'd love to take a bath with her sometime… Maybe brush each other's hair, appreciating the newfound sense of femininity in the blue-haired girl's endearing behavior. 

The idea made her cheeks warm, and she quickly shook her head.

Focus!

But no matter how much she tried to stay grounded, the truth was becoming clearer by the second.

This wasn't just reincarnation. It was something else entirely.

She hadn't been born again as a baby or tossed into some random fantasy world with nothing but memories to guide her.

She had been transferred.

Her own soul had somehow merged with Su Mu's. She could feel the truth of it in every breath, every movement. 

Su Mu's memories were becoming part of her now—events, emotions, habits—like echoes that grew stronger the more she accepted them.

And yet, she hadn't lost herself either.

'I'm still me… but I'm also her.' The thought was dizzying, strange… but also kind of amazing.

She looked down at her delicate hands—no longer those of a worn-out developer, but slender and graceful, the hands of a noble lady.

A weird mix of anxiety and curiosity fluttered in her chest.

But one thing was certain now: Su Yang's life had ended, and Su Mu's had begun again—with her in it.

Instead of rejecting that, she found herself thinking, 'Maybe I don't have to give up everything I used to be.'

"Even though this body is Su Mu's," she thought quietly, "I still have all of my own memories, my thoughts, my personality. Maybe I can combine the two. I don't have to be just one or the other."

The idea brought a strange kind of comfort.

She didn't want to erase Su Mu… but she didn't want to disappear either.

There was something exciting about the chance to live again, to really live, but this time in a world that looked like it came straight out of a fantasy novel.

No endless crunch time, no deadlines, no ramen-fueled all-nighters staring at code. Just... life as a noble lady in a peaceful world.

"Back in my old world… dying didn't really scare me. It felt empty in the end. I didn't have much to lose. No girlfriend. No real connections. Just work."

Her expression softened, filled with wonder as she looked around again at the luxurious room, the sunlight casting golden patterns on the carpet, the faint smell of flowers from a vase nearby.

"But here… Su Mu had everything. A loving household. Friends. A peaceful life."

It wasn't just another life. It was a better one.

And now it was hers.

She turned to Meiling, who was still fidgeting beside her, clearly trying to pretend the whole spider thing never happened.

"Hey, Lingxi," she said softly.

Meiling looked up. "Yes, Miss?"

Su Mu smiled. "Thanks for coming in so quickly. I… think I needed someone familiar right now."

Meiling's eyes softened, and she gave a gentle nod. "Of course, Miss Su Mu. Always."

And in that moment, for the first time since waking up in this strange body, Su Yang—now Su Mu—felt like maybe, just maybe… everything might turn out alright.

"Miss Su Mu, how can you leave your room without calling me first? And you're still in your nightwear?" Lingxi's voice carried a mix of scolding and concern as she stepped forward, her eyes widening slightly.

Her tone wasn't angry—more worried than anything. 

The way she furrowed her brows showed how much she cared. "You must still be feeling off from the Spiritual Awakening yesterday," she said more softly now, her expression relaxing.

"But… you should've followed the Spiritual Master's instructions. Come with me. The lady will explain everything."

Before Su Mu could say anything else, Lingxi gently took her hand and began to lead her down the corridor. 

The touch was warm and surprisingly comforting—like being led by an old friend, even if they'd only just really met in this lifetime.

All thanks to the memories of Su Mu, merging with her faster than she thought.

Then, from around the corner, someone appeared—someone who made the whole atmosphere shift in an instant.

A tall woman, radiating elegance, stepped into view. 

She wore a deep violet halter gown that shimmered like moonlight, hugging her figure and flowing like silk in the breeze. 

Every step she took was graceful, like she didn't walk but floated.

Her silver hair tumbled like a waterfall down her back, and her face, so refined and poised, bore wisdom, strength, and a quiet beauty. 

She didn't need to speak to demand respect—it just happened naturally. 

Su Mu's breath caught in her throat. She didn't even need to ask. She knew instinctively:

This was her mother.

"Ah, Mu'er," the woman said with a cool, melodic voice that carried both worry and command, "you're finally awake. How are you feeling now?"

Su Mu's heart pounded. This wasn't just someone important, this was her mother in this world. Someone who loved her. Someone who had been taking care of her all her life.

Observing her carefully, one could discern a striking resemblance, as if Su Mu had inherited 70 to 80% of her features.
