"Could this kind of encounter actually... be possible?" She works at a daycare, and he's a freelance writer. They meet when he comes to pick up his brother's child, whom he lives with, from her daycare. Bonding over interactions with his nephew, their relationship quickly progresses. They start dating, and since she's had few opportunities to meet people, she takes the initiative right from their first meeting. Their dates at amusement parks and aquariums excite her more and more, building her emotions higher and higher. At dusk, they share a kiss in the park, igniting intense chemistry between them. Carried away by the passion, they end up at a hotel and experience sex together for the first time. This naturally unfolding relationship leaves a deep mark on both their hearts.
