In spanish theres a bonus skill for flirting, if there isnt one in norwegian, there totally should be. It can include such things as "<person> is my date/boyfriend/girlfriend" and "i love you" and "do you want to go on a date with me" also, as was in the spanish one, "I do not need to read your terms of service to accept you" or something like "if a wolf is eating you, i'd save you"
"han" is used like the English "he" and "him".
The completely optional word "ham" can be used in place of "han" when you would use the English "him".
It doesn't always have to mean "love" in a romantic way. It can however be used to express other kinds of love, such as loving a song, or a type of food. Eg. Jeg elsker iskrem. Typically, elsker is used to translate the highest degree of love or affection for any one thing.
