Often, in these fanfictions, Katniss will sacrifice something for Peeta. For example, if there's a limited supply of a certain medicine in the district, and Peeta is sick, she might give up her chance to get it for herself in order to help him. This selfless act clearly shows her love for him before the games even start.
One common scenario is when Peeta is injured. Katniss has to take care of him, and during this time, she realizes how much he means to her.

One common scenario is when Katniss nurses Peeta back to health. This shows her care and love as she devotes time and energy to making sure he recovers.

Perhaps a scenario where they are dealing with the psychological aftermath of the Games without actually being in them.

Maybe they kiss in a secret hiding place within the Capitol. They are hiding from the Capitol's forces and in that moment of fear and closeness, their feelings overpower them and they share a kiss. This would add an element of danger and secrecy to their relationship.
