The relationship could start with a misunderstanding. For example, the OC could think that Ryou is a bit of a cold - hearted boss at the café where she works, but then she discovers his kind side when he helps her rescue a stray cat. This moment of seeing his true nature could be the start of her developing feelings for him.
Imagine a fanfiction where Ryou is sick, and Ichigo decides to take care of him. She brings him some lemon tea to help him feel better. As she takes care of him, they start to have deeper conversations. The lemon tea becomes a symbol of her care for him, and this experience brings them closer together. It could be a really sweet and tender story about their relationship developing.
In many Tokyo Mew Mew fanfictions, Ichigo and Ryou's relationship is a popular topic. A kiss between them could be a very emotional moment. It might happen after a big battle where they realize their deep feelings for each other. Maybe Ryou saves Ichigo from a dangerous situation and in the heat of the moment, they share a kiss. This would be a significant development in their relationship as they have a lot of unspoken chemistry in the original series.
One possible fanfiction could be that Ryou and Ichigo go on a special mission together. Along the way, they discover a new type of alien creature that is causing trouble in the city. The 'lemon' aspect could be added in a light - hearted way, like they share a lemon - flavored treat during a break in their mission, which leads to a cute and flirty moment between them.
One possible fanfiction could be about Ichigo and Ryou going on a secret adventure together. Maybe they discover a new type of alien that the other Mew Mews haven't encountered yet. They would have to rely on their unique bond and powers to deal with it.
A simple fanfiction idea could be that Ichigo and Ryou start dating secretly. They have to hide their relationship from the other Mew Mews at first because they are not sure how everyone will react.
A third plot might be that the OC is a normal girl who has a special connection to the Mew Mew project. Ryou hires her to work at the café, not realizing that she has a hidden power. As they work together, they start to get closer. But then an old enemy of the Mew Mews resurfaces and targets the OC. Ryou has to protect her and in the process, their relationship deepens.
One possible reason could be jealousy. If another character shows interest in Ichigo, Ryou might become jealous and finally act on his feelings, leading to a kiss. For example, if a new Mew Mew joins the team and gets too close to Ichigo, Ryou would feel the need to assert his claim on her.
Well, in such a fanfiction scenario, it could be a really intense encounter. Maybe the 'hurt reader' is in a vulnerable state, and Kisshu's appearance adds a whole new layer of complexity. It could lead to a situation where the reader is both scared and intrigued by Kisshu, and their meeting might be the start of a wild adventure within the Tokyo Mew Mew universe.
In Tokyo Mew Mew fanfiction regarding Kisshu and Ichigo's romance, the writers often take creative liberties. They might change the circumstances of their first meeting or add new obstacles to their relationship. For example, some fanfictions could have Ichigo having to choose between Kisshu and another character. Or Kisshu might have to prove himself worthy of Ichigo's love by helping the Mew Mew team. This way, the fanfiction adds new layers to their relationship.
