Nothing ultimately serious; so nothing where they break up or actually get close to breaking up (though it's okay if they each worry about it after the fight). Just normal fights, ranging from silly to honest frustration and anger, where one or both of them are yelling, or someone says something that hurts the other one's feelings, accidentally or on purpose.
Any kind of non-break up fight, with making up (with words and/or sex) at the end.
Any length, short or long; AU or not. Thank you for any recs!
For example: Kiss the Rain by heartsmadeofbooks, which I love.
