Takou no Koori-hime wo Tasuketara, Otomodachi kara Hajimeru Koto ni Narimashita

Nagi Shinonome is widely known among her peers as the "Ice Princess," a strikingly beautiful girl whose perpetually cold demeanor keeps everyone at a distance. She struggles to connect with those around her, preferring a solitary existence over forced social interactions. However, her isolated world is unexpectedly disrupted when Sota Minoru, an ordinary classmate, witnesses her being harassed by a stranger on a crowded train. Rather than looking away like everyone else, Sota gathers his courage and steps in to protect her, forever altering the dynamic between them. The following day, Nagi approaches Sota with a request that catches him entirely off guard. Dropping her usual icy facade, she asks him simply to stay by her side. This earnest plea marks the beginning of an unusual arrangement, as Sota resolves to maintain their relationship strictly within the boundaries of friendship. Yet, navigating this promise proves increasingly difficult when he realizes that the aloof Ice Princess has begun to melt, revealing a surprisingly sweet and affectionate side reserved solely for him. As Nagi's warmth continues to grow, Sota must struggle to uphold his original intentions while facing the undeniable charm of a girl who only softens in his presence.
