Luca Graven, an orphan cursed by poverty, worked under the man loathed the most— Dante Solis. He was a wealthy, powerful mafia leader who had the strongest men, including Luca himself cowering in fear. Unfortunately, Dante took a liking to him. He brought him into his home, enslaved him, treated him like rubbish….but, he never hurt him beyond his limits. Maybe that was why Luca never fully hated him, and maybe, just maybe, that was why he wanted him. Until, a new version of him shows up. He looked exactly like Dante, same voice even, but completely different personalities. This version listened, cared for him, no longer saw him as a mere slave, he nurtured him and treated him like he meant something for once. Of course to Luca, Dante had miraculously grown a heart but that person that showed him kindness and mercy wasn’t Dante. It was Allen Pierce—his doppelganger. Now torn between two different people, yet drawn to each of them and their different souls, he has to make a decision. But they don’t make it easy. Luca wasn’t the only one fighting to choose, they were both fighting to be chosen.

When I find out there's a tumor growing in my brain, the Kane sisters are in the middle of celebrating Evan Kennedy's birthday with him. If I undergo the tumor-extracting surgery, I'll risk losing my memories. I don't want to forget the sisters at all, so I call them in hopes of seeking their help. But all three sisters don't hesitate to berate me on the spot. "Why can't you be more understanding, Declan? It's Evan's birthday today! Nothing is more important than his birthday!" Heartbroken, I feel immense pain wrecking my head. That's how I end up collapsing three times in a row later on. When I regain my consciousness in the hospital, I see a text message sent by Evan. "Declan, the Kane sisters have given me three protective charms just to protect me." In the photo, the "protective charms" are actually the very same charms I have managed to obtain after spending ten hours climbing a mountain while groveling all the way. My heart has officially died at that moment. So, I decide to fly overseas on my own to undergo that life-saving surgery and forget all about the Kanes. Weirdly enough, the sisters go crazy right after I've forgotten about them.

In the end, she misses her liberal arts examination. Driven to despair, she jumps to her death. Later, my boyfriend and I are both admitted to Bloomdale University, the best university in the country. We build successful careers and earn seven-figure salaries—our marriage is perfect. However, on the death anniversary of my boyfriend's childhood friend, he stabs me repeatedly, taking my life. "It was your fault she died," he says. "If I had gone back to get Ginger's admission pass, she wouldn't have lost hope and taken her life." When I open my eyes again, I realize I am back on the same day of the examination. My boyfriend's anxious voice rings in my ear. "Amelia, I need to go back to get Ginger's examination admission pass." This time, I smile and say, "Go ahead. Please be careful."

When Elowen learned that she had been switched at birth, that her life as a princess was nothing more than a mistake, she quietly accepted her fate. She accepted being treated as an error. Accepted being hurt so deeply that even crying had to be done in secret. She believed she would fade away like this — silently, unnoticed, forgotten. Until one day — when despair pushed her to the edge — she felt a faint chill, as if someone were standing behind her, protecting her without a word. From that moment on, Elowen knew she was no longer alone. — Adrian survived a horrific car accident. His body lay motionless in a hospital bed, while his soul became bound to a wounded girl he had never known. He couldn’t hold her. Couldn’t shield her from harm. Yet when she was starved, warm food appeared in her drawer. When she was bullied, her tormentors met with inexplicable accidents. When she curled up crying in the dead of night, an invisible hand gently rested on her forehead—so tender it hurt. Adrian was there. Quieter than any living person. He witnessed every wound, remembered every tear, every trembling breath she tried to suppress. Affection grew in silence—slowly, carefully—as if one careless step closer would cause the girl to shatter. One was alive, yet denied a life. One was dead, yet still learning how to protect someone. Some forms of protection need no light. Some kinds of love cannot be touched. — Then one day, Elowen spoke seriously to her “Ms. Ghost”: Elowen: “Ms. Ghost, if you’re lonely…” “Maybe you could bond with a male ghost.” “I’d give you my blessing.” Adrian: … Then the “Ms. Ghost” coldly placed a hand on her forehead. Adrian: “Call me Mr. Ghost.”
