One possible scenario in a Loki x Balder fanfiction could be their initial encounter. Maybe Loki, with his mischievous nature, tries to play a prank on Balder, but Balder's pure and kind heart makes Loki's attempt backfire in an unexpected way. This could lead to an interesting dynamic where Loki starts to see Balder in a new light.
Similar to the novel Base 7, there were recommendations such as Spirit Realm Walker, Light Barrier, King of Firepower, Sky Splitting Sky Rider, Celestial Master Yuan, and so on.
Another fanfic idea could be a more romantic one. For example, Balder is initially hesitant to show his feelings for Yui because of his status as a god, but as time passes, he can't resist his emotions any longer. Yui, on the other hand, has always been secretly in love with Balder and when he finally makes a move, it's a beautiful moment of two different worlds coming together in love.

In romance novels, first base, second base, and third base usually referred to the three positions on the softball field. First base is the first base that faces up, second base is the second base that faces up, and third base is the third base that faces up. In novels, these positions were often used to describe the places or scenes where the characters were located and to hint at the relationships between the characters.
There was usually a "home plate" between first base and second base, which was the home plate where the character was. In the home plate, the character can attack the opponent at will, but if the opponent hits the home plate, the character will be directly eliminated. In third base, the character could not attack the opponent, but if the opponent hit the third base, the character would be directly eliminated.
