A simple plot could be that Natsu and Lucy are exploring a new area and stumble upon a hidden lemon hot spring. They decide to take a dip. While in the hot spring, they notice some strange glowing fish in the water. Natsu wants to catch one, but Lucy warns him not to. Of course, Natsu being Natsu, he tries anyway and ends up causing a bit of chaos in the hot spring.
For a more complex plot, the lemon hot spring could be a place of power. Natsu and Lucy are sent there by the guild master to investigate some strange energy readings. Once in the hot spring, they find that the lemon - scented steam is affecting their magic in different ways. Natsu's fire becomes more intense, and Lucy's celestial spirits seem more powerful. They have to figure out how to control these new powers while also dealing with some mysterious creatures that lurk in the hot spring. This adventure could bring them closer together as they rely on each other's strengths.
Another plot idea is that the lemon hot spring is a place of healing. Natsu has been injured on a mission, and Lucy takes him to the hot spring which is known for its restorative properties. As Natsu heals, they talk about their dreams and fears. Lucy realizes how much Natsu has been through, and Natsu appreciates Lucy's kindness more than ever. This could be a turning point in their relationship, where they start to see each other in a different light and perhaps develop deeper feelings for one another.
In this fanfiction scenario, Natsu and Lucy might have a relaxing time in the lemon - scented hot spring. They could start with some light banter, Natsu being his usual energetic self while Lucy is a bit more reserved at first. Maybe they share stories about their recent quests and gradually grow closer in this serene setting.
In a fanfiction scenario, they could be at the lemon - scented hot spring alone, and Natsu discovers that the hot spring has some sort of magical property that makes him more in touch with his emotions. He then starts to confess to Lucy how much he values her as a teammate and friend, but in a more heartfelt way than usual. Lucy is touched and they have a really sweet moment together.
In the fanfiction, the lemon hot spring could be a place of peace for Natsu and Lucy. The lemon essence in the water could have a rejuvenating effect on them. Natsu could show his protective side towards Lucy in this setting. For example, if there were any small creatures around that seemed threatening, he would be on guard. And Lucy, in turn, could share her thoughts on the beauty of the place with Natsu, deepening their friendship.
One possible plot could be that Natsu and Lucy go on a dangerous mission together. In the middle of it, they find a mysterious lemon - like magical item. As they study it, they start to feel a strange warmth between them. They then have to overcome their initial shyness and admit their feelings for each other while dealing with the power of this strange item.
I'm not sure specifically as I haven't read this particular fanfiction. But generally, it might involve Natsu and Lucy having some sort of adventure or interaction at a lemon spa. Maybe they go there to relax after a tough mission and something unexpected occurs during their time at the spa.
One good story could be 'Natsu and Lucy's Adventure in the Lemon Grove'. In this fanfiction, Natsu and Lucy find themselves in a magical lemon grove where they have to solve a mystery related to the hot lemons. It has a lot of sweet and adventurous moments between them.
The main characters are clearly Natsu and Lucy. Natsu is a powerful dragon slayer with a fiery personality. He's impulsive and brave. Lucy is a celestial wizard. She's smart and kind - hearted. Together, they form an interesting pair in the fanfic.
In fanfiction, Natsu and Lucy at the spa could be a really fun scenario. Maybe they go to the spa after a tough mission. Natsu, being his energetic self, might be a bit out of place in the calm spa environment at first. But with Lucy's guidance, he starts to relax. They could share some funny moments like Natsu accidentally making a big splash in the hot tub or getting confused by all the different scented oils. It's a great opportunity for their relationship to grow in a more relaxed and non - combat setting.
