When the week ends and the couple accepts the bond, the Mark ceases to be a test and transforms into a pact. The red cord doesn't disappear, but changes in intensity, becoming thinner and softer, allowing them to move up to ten meters apart without pain or resistance. It remains visible only to the two of them, constantly reminding them of the connection they share. Mental communication remains, but becomes more stable and clear. They no longer need to concentrate so much to listen to each other; a focused thought is enough. Over time, they learn to disconnect when they need privacy, something that is only possible because there has been mutual acceptance. Emotions cease to be intrusive and begin to function as support. In moments of anxiety or sadness, the other person senses it and can offer almost immediate comfort. Heartbeats remain synchronized when they are close, but now this brings calm instead of discomfort. The luminous symbol of the fifth day settles on the skin like a permanent mark, glowing softly when they are side by side. It is said that, when the bond is true, the glow intensifies during moments of genuine happiness. From then on, the relationship ceases to be imposed by fate and begins to depend on the choices of the two, but the Mark guarantees that they will never be completely alone as long as they walk together, and upon reaching 16 years of age, they all become hybrids with the animal most similar to them.

Day 1: A small tuft of hair changes to an unusual color, and your soulmate instantly receives the exact same shade. This is the first visible sign, but several people may have similar hair colors, so there's still no way to be absolutely certain who your soulmate is. Day 2: All those marked develop temporary hybrid traits based on the animal that best matches their personality or essence. Ears, a tail, discreet fangs, eyes with different pupils, or small physical changes may appear. The soulmate manifests compatible or complementary characteristics, but since many students also become hybrids on this day, it remains difficult to be 100% certain. Day 3: Mental communication awakens. Thoughts can be sent and received clearly, but unseen rules prevent you from revealing names, detailed appearance, or any information that directly identifies you. Day 4: The most chaotic effect emerges. At random moments, the soulmates switch bodies for a few minutes. This can happen a few or several times throughout the day. It's the first really strong clue to the pair's identity. Day 5: An identical luminous symbol appears on both of their skin. It glows softly and intensifies when they are physically close. Day 6: A clear sense of direction and proximity emerges. Even without visual contact, both can roughly sense where the other is and when they are approaching or moving away, like a much more precise instinctive compass. Day 7: A red cord forms, connecting the two and preventing them from straying more than a meter apart. Furthermore, the hybrid traits from Day 2 cease to be temporary and become permanent from this moment on, definitively marking the connection between the soulmates.

Amy is known as the school's bully, the richest girl, and the queen bee. Always impeccably dressed, her uniform perfectly tailored, with a sharp gaze and the posture of someone who knows everyone is watching her. She walks the hallways as if they were catwalks and speaks as if every word were an order. She does what she wants, when she wants. Her parents are filthy rich and her uncle is the principal, so she almost never faces real consequences. She lives surrounded by people, especially at lavish parties in the family mansion, extravagant events that often end in scandals, rumors, and someone crying the next day. But that image is a facade. Deep down, Amy is just a girl terrified of the idea of ​​being alone again. Two years ago, the family business suffered temporary bankruptcy after a disastrous investment and an unexpected court injunction. Accounts were frozen, cars sold, employees laid off. The news spread quickly. Within weeks, the “friends” who lived in her house disappeared. Invitations vanished, messages went unanswered. People who swore loyalty began spreading cruel rumors, saying she was nobody without money. Amy saw firsthand how affection was conditional on status. When the financial situation was resolved and the fortune returned even greater, the same faces returned smiling as if nothing had happened. It was at that moment that she decided she would never again be the vulnerable girl who begged for company. She preferred to be feared than to be discarded. Since then, she controls everything around her, keeps everyone close, but never too close. Because, deep down, Amy's greatest fear is not losing power. It's waking up one day and realizing that, once again, she's alone, her friends Zoe and Mika are truly her friends, and her favorite animal is a fox.

When the twin tries to replace her with another, the Mark begins to react erratically. At the first sign of rejection, the tuft of hair loses its shine and the color begins to fade, as if the connection were weakening. The clothes cease to synchronize perfectly and begin to alternate shades irregularly. If the person insists on forcing a new bond, the mental connection of the third day becomes noisy, with jumbled thoughts and confused sensations, making it difficult to distinguish what is theirs and what comes from the former partner. The echoing emotions of the fourth day transform into discomfort, generating pressure in the chest whenever they try to ignore the original bond. In the most advanced stage of rejection, the luminous symbol of the fifth day fragments, revealing cracks of light on the skin that sting slightly. The synchronized heartbeats of the sixth day become erratic, causing fatigue and a constant feeling of emptiness. If the person attempts to formalize the exchange with another, the red cord of the seventh day does not form with the newly chosen one. Instead, a thin, fragile, pale line appears, which breaks easily. The Mark then fades completely, preventing any new true connection until the mistake is acknowledged or fate intervenes again.
