Attention Sir, I Have Your Heart Handcuffed! - Chapter 23. I will find you, no matter what.

Aiden Nightshade wakes up in a dark, unfamiliar forest with no memories of who he is or how he got there. The air is thick with danger, and monstrous creatures lurk in the shadows, watching him. Before he can even move, a glowing panel appears in front of him.[Welcome to the Ultimate Bond System.]A cold, synthetic female voice echoes in his mind. It tells him to tame the beasts, bond with them, and grow stronger together. But this system isn’t normal. When Aiden forms a bond with a beast, it doesn’t just become his companion—it transforms into a powerful humanoid woman, one who still has the instincts and memories of the creature she once was. They aren’t just allies. They feel his pain, share his power, and their devotion to him is absolute.As Aiden explores this strange world, he quickly realizes something—no one else can do what he does. Other tamers can control beasts, but they can’t make them evolve like he can. They do have a system but nothing like his.With his growing army of beast-women by his side, Aiden will carve his own path, breaking the rules of this world. And when he discovers that the deepest bonds unlock unimaginable strength, he understands one thing—this isn’t just about surviving.It’s about rising above everything. It’s about domination.In a world ruled by beasts, only one man will stand at the top.

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory?

His exceptional athleticism and magical aptitude promise a powerful Talent – a guarantee for a secure life and social status.But fate had different plans. During Alister's Awakening ceremony, it's revealed that he's a Summoner. Instead of admiration, he faces mockery. His once bright future turns bleak as his “friends” desert him for Talents they see as more “useful.”left alone, Alister awakens a system.[Host found, system binding...][System binded successfully.][Congrats, you have gain the status of 'player'.][Ding!! Congrats to the player for awakening The Dragonforge - an overlord system.][Ding!! it has been detected that the player possesses a latent draconic aspect, and as such will only be able to summon dragons!!][Will the player like to proceed with their first summoning?]Cast aside and underestimated, Alister becomes a force to be reckoned with. He embarks on a journey, building his own dragon army – a crew of majestic wyverns, fearsome drakes, and ancient wyrms. He raids the wastelands, reclaims lost resources, and dismantles the prejudice against summoners. Every day, his power grows, his bond with his dragons deepens, and his legend spreads like wildfire.

Aliandra Amariel loved magic, dedicating her academic years to the study of runes and spells, pushing the boundaries of mana's infinite possibilities. Like most Fae, her destiny seemed clear until that fateful day of her Class Trial, when the Blind Lich unleashed an undead apocalypse on her home, the fabled underground city of Dal’mohra, and triggered The Breaking – a cataclysm that forever reshaped the world. Saved by her mother’s legendary time-stasis spell, Ali wakes thousands of years into a dark future. Everything she knew and loved is gone, buried under a mountain, transformed into a twisted dungeon by the malevolent will of the Lich. Now, Ali must confront her deepest fears, mastering the arts of battling monsters and braving a town riddled with corruption. As the Lich's grand design shadows her every move, she scrambles to forge new friendships and unearth ancient knowledge in her fight for survival. Why must she struggle? All she had ever wanted was to curl up in a comfy chair with a few thousand good books. But the immortal Lich is drawn to her unique magic, ever hungry for more power to fuel his cold-hearted ambitions. How will she survive the giant target painted on her back as her advancement slowly reveals the horrifying truth of the Class she chose to save herself? Will she falter, forced into the eternal servitude of undeath, or will she rise against all odds and cast him down, ridding the world of his evil?
