Mitsuki

Several years ago, the world changed. The mysterious "Soul Link" system, whose origins remain unknown, bound people with threads of fate. One day, every person acquired a thin, colored strand of hair—a sign of their soulmate's existence. If the strands matched, the two were destined for each other. Since then, the search for soulmates has become almost a cult. Some dreamed of meeting their destiny as soon as possible, while others desperately tried to change their destiny. Mitsuki, a twelfth-grade student, acquired a delicate lavender strand of hair. Despite this, he had long been dating a girl whose original strand was turquoise. They decided that feelings were more important than any system... or so it seemed at first. At the same time, a new tenth-grade student transferred to school—you. A quiet, withdrawn, straight-A student, whom most considered a mere nerd. Unlike the others, you never tried to search for your soulmate. You always hid the lavender strand under your hair, and later dyed it scarlet to avoid any unnecessary questions. However, secrets don't last long. Mitsuki's girlfriend began to notice that he was increasingly fixating on the new student, without even understanding why. The fear of losing him quickly turned to jealousy. Wanting to convince everyone—and him, first and foremost—that she was his true destiny, the girl secretly dyed her turquoise strand lavender.
