Ryou Fujihashi awakes to the sight of her apartment ablaze with smoke swirling and heat pressing. With no escape route, she shouts as loudly as possible to warn neighbors. Luckily someone has already dialed the fire brigade, and they arrive quickly to pull her out.
In an unexpected turn of events, one of the rescuers is actually Souma Mizuno, her childhood companion. Ryou once had a fleeting crush on him, but his notorious flirtatious nature put it to an end. Now that Ryou has lost everything and no longer has a home, Souma offers his place to her. Living beside the boy she grew up with forces Ryou to establish clear physical limits, for crossing them would lead straight into Souma's passionate embrace. Yet his unwavering attention stirs the possibility of rekindling old flames between them.
As she becomes closer to Souma, she also finds herself mingling with the rest of the attractive fire crew. Though Souma's affection is fixed on Ryou, can she keep her own heart from drifting elsewhere?
