Chapter 1

My parents divorced when I was a kid. When I was ten, my mom dumped me on her best friend, Sienna, and vanished without a trace.

Sienna, who is only ten years older than me, gave up her youth, her dating life, and any hope of marriage just to raise me.

But the other day, she came to visit my rented apartment. It just so happened that my male colleague was crashing at my place.

She completely misunderstood my sexuality, thinking I was into guys. Determined to "save" me and prove how amazing women are, she squeezed into my bed that night, whispering that she was going to show me what I was missing...

For as long as I can remember, my parents were divorced. I lived with my mom.

But when I turned ten, my mom, Diana, handed me over to her best friend, Sienna, and disappeared. I never heard from her again.

I knew my mom just wanted to get rid of her baggage. Yet, Sienna chose to stay. She took me in and raised me with nothing but love and care.

Sienna is exactly ten years older than me. She is breathtakingly beautiful—a perfect heart-shaped face, soft arched brows, flawless porcelain skin, and a body that could stop traffic. With her long legs, tiny waist, and curves in all the right places, she is hands down the most beautiful woman I’ve ever seen.

Growing up with such a gorgeous woman was fine when I was a clueless kid. But once puberty hit, my teenage hormones raged. Sienna inevitably became the star of my secret fantasies.

I knew it was wrong. But the harder I tried to stop, the more vivid those scandalous thoughts became.

It was only when I moved into the college dorms that I finally got some control over myself.

Over the years, I never saw Sienna date anyone. She poured all her time and energy into me.

To me, Sienna was the definition of perfect—kind, gentle, and utterly stunning. A literal goddess.

I swore to myself that once I made it big, I would spoil her and make sure she lived the happiest life possible.

But before I could even make my first million, an unexpected incident flipped our relationship upside down.

It started when my coworker, Ethan, asked if he could crash at my place for a few days because his lease was up. It was hard to say no, so I agreed. He packed his bags and moved in that very afternoon.

After moving all his stuff, Ethan was dripping with sweat. He rushed into the bathroom to take a shower, only to realize he had forgotten his clothes.

"Leo, man! Lend me a pair of boxers. I’ll grab my clothes in a second!"

Ethan poked his head out of the bathroom door and yelled.

I rolled my eyes, sighed, and went to my closet to grab him a clean pair of boxers.

A few minutes later, Ethan walked out of the bathroom shirtless, tugging at the waistband.

"Hey Leo, these actually fit pretty well."

Before I could reply, the sound of a key turning in the front door echoed through the room.

My heart skipped a beat. Was I hallucinating? No, someone was definitely unlocking my door.

What the hell? Was it a burglar?

*Click.* The door swung open, and a stunning figure stepped inside.

It was Sienna. She was wearing a sleek, form-fitting trench coat, black sheer tights, and killer high heels. Her long, silky black hair fell gracefully over her shoulders, framing her gorgeous face.

But the second she saw me and then locked eyes with a shirtless Ethan, her expression froze into utter shock and panic.

When I graduated from college and got a job in this city, Sienna was so worried about me that she drove me here herself and helped me find a place.

I had planned to rent a sketchy studio in a rough neighborhood to save money, but Sienna put her foot down. She rented me a nice, cozy apartment near my office and paid the deposit and three months' rent.

Before she left, she kept a spare key, saying she’d drop by whenever she had time. I thought she was just saying that. I never expected her to actually show up.

And definitely not at a moment like this.

I quickly rushed over to greet her, my heart racing. "Sienna! What are you doing here?"

"What, am I not welcome?"

Sienna pouted, her voice laced with a hint of playful annoyance.

"No, of course not!" I quickly denied. "I'm incredibly happy to see you."

"Are you?" Sienna raised an eyebrow, her gaze shifting from Ethan back to me. "I hope I didn’t... interrupt anything."

Before I could explain, Ethan’s eyes lit up, and he practically bounced over. "Leo, who is this gorgeous lady?"

"This is Sienna."

Out of politeness, I had no choice but to introduce them, feeling incredibly awkward.

Ethan was instantly overly enthusiastic, hyping up our friendship like we were brothers who had gone to war together.

Sienna didn’t say much. She just gave him a cold, polite nod.

Sienna never gave other men the time of day. If it weren't for me, she wouldn't have even acknowledged his existence.

"Alright, Ethan. You should get going. We'll talk later."

Seeing how tense the atmosphere was, I practically dragged Ethan to the door and pushed him out.

When I walked back into the living room, Sienna was sitting on the couch, her long legs crossed, still looking annoyed.

I thought she was mad because I had let someone move in without telling her, so I quickly explained.

"Sienna, Ethan is just a colleague. We’re good friends, and he’s in between apartments. He was just looking for a place to crash for a couple of days. He hasn't even officially moved in yet."

Hearing my explanation, the tension on Sienna’s face melted away, replaced by a soft smile.

"Well, I was planning to just check on you and leave. But now, I’ve decided to stay here with you for a while."
