5-tsu no Hajimete: Ubawarete mo Ii, Kimi ni Nara

Akane is a young woman whose life has been heavily defined by her fragile health. Frequently ill and confined by her physical limitations, she has lived largely sheltered from the world, leaving her entirely inexperienced when it comes to romance. Having never navigated the complexities of relationships or matters of the heart, she approaches love as an absolute beginner, unsure of what to expect or how to handle the emotions involved. Her quiet existence takes an unexpected turn when she encounters a boy with a strikingly intense and almost demonic demeanor. Far from being intimidated by his fearsome nature, Akane finds herself drawn into a deeply unusual dynamic with him. In a surprising twist of fate, the very girl who knows nothing about romance becomes the one tasked with teaching this formidable, devilish young man about the true meaning of love. As their bond develops, Akane discovers a profound sense of devotion that overrides her usual reservations. Despite her inexperience and delicate condition, she reaches a heartfelt realization: she is willing to surrender everything she has, even allowing herself to be completely consumed by him, as long as he is the one taking it all.
