Rom where the ML/FL are stuck to the hipbone

Like they're together in almost every scene of the drama from young to old and have all the talks/growing up/closer scenses together, and not like the typical love triangle where the FL has all the romatic/cute/lovely accidents with the ML but the SML gets to have the get to knowing scenes. 

Something like Douluo Continent, The Great Ruler, Sweet First Love, or Twisted Fate of Love where the FL basically is fated from the beginning to have a relationship with the ML.
