The depression series was originally intended to be a darkening series, but one pair was really sweet (although they were still Be), so they were mainly used to treat (cause) healing (depression).
The first couple is Heihua Hidden Sword x Scumbag Tiance. They were originally a couple, but I think they were really sweet when they first fell in love, but later Tiance changed, so the Tiance that the senior brother loved has long since disappeared, so there is no point in forcing the relationship.
The second countermeasure was super sweet when I first opened my imagination. It was the kind of pure first love when we met each other, and there was no betrayal or killing each other... So they were separated by yin and yang, alas.
In addition to these two pairs, there are other CPs, such as Ba Du (the famous prodigal Ba Dao x the fledgling Xiantian and then the five black poisons, true be and false he), GL straight girl Tiance x the black hidden sword, Ceme (the serious urban management Tiance x the little Taoist priest who always gets betrayed when telling the truth).
Just read and update as circumstances dictate, and see when I can finish updating these pairs.
