In 'A Day in the City', they go around the city together, just having normal conversations and getting to know each other better outside of the hero context.

In many fanfics, a great moment is when Izuku and Momo first combine their powers in a fight. It's really exciting to see how Izuku's determination and Momo's intelligence work together.

One great 'Boku no Hero Academia Izuku' fanfic could be one where Izuku discovers a new, hidden quirk within himself that's not related to One For All. This could lead to him having to train in a completely different way and form new relationships with his classmates as they all try to figure out this new aspect of his powers.
I've also read 'The Unlikely Duo'. This fanfic takes a different approach. It starts with Izuku and Momo being paired up for a project that has nothing to do with hero work. They initially clash because of their different personalities, but as they get to know each other better, they start to realize they have a lot in common and a relationship slowly blossoms.

One common emotional moment is when Izuku is physically injured during a battle. In some fanfictions, he might be seriously hurt while protecting his friends. This shows his selfless nature and makes readers feel for his pain.
A fanfic could be set during a school festival. Momo is in charge of one of the booths and Todoroki volunteers to help her. They have to deal with various problems like running out of supplies. Momo creates new items with her quirk while Todoroki helps with keeping things cool (literally with his ice) or heating up things when needed. In the process, they share some personal stories and get closer, realizing they have more in common than they thought.
One common theme is growth. Both Izuku and Tsuyu are characters who are constantly evolving in the original series, and in fanfiction, this growth is often explored further. For example, they might grow not just as heroes, but also in their relationship with each other.
There's also 'Growth and Love in U.A.'. In this fanfiction, it focuses on their daily lives at U.A. High School. Midoriya helps Momo with her confidence in using her quirk, and as they spend more time together, they realize they have feelings for each other. It shows their character development intertwined with their budding romance.
