Well, it could be about the unexpected bond between Kara and the cat. Maybe it's a story of how a kiss symbolizes a special connection, like a magical or telepathic link.

Perhaps a storyline where Momo is in trouble and Izuku saves her. In the aftermath, with all the emotions running high, they kiss.

One possible plot could be that Lena and Kara are in a dangerous situation together. As they face a powerful enemy, they realize their deep feelings for each other. In a moment of intense emotion, perhaps after one saves the other's life, they share a kiss.

One possible plot could be that they are in a dangerous situation together. Izuku uses his powers to protect Diana, and in that moment of relief after the danger has passed, they share a kiss. It's a moment of pure emotion and connection.
There could be a plot where the kiss is a moment of confusion for both Kara and Lena at first. But then they start to have dreams about each other that reveal their hidden desires. They then decide to explore their relationship further. Along the way, they might discover that their combined powers, not just Kara's superpowers but also Lena's intelligence and skills, can be used to create a new form of energy that could save the world. But they also have to deal with their own insecurities and the expectations of others.
Another idea is Kara getting separated from Alice and Connor during their journey to freedom. She then has to rely on her own wits and the kindness of some humans she meets along the way.

It would be a great exploration of her character's growth and her ability to adapt in tough situations.
