单向宣战 (Dānxiàng Xuānzhàn)

Background
"I was thinking about this: since you gave her the warmth she never felt before, why did she not rant to you about this event that angered her"

- Author's note (translated by laterallanterns)

"Dānxiàng Xuānzhàn" is an original YANHE song. It is the third song of the Bidirectional Series. It was intended to follow Yuezheng Ling's point of view.

In the song, Ling expresses her deep love for YANHE, but knows that he loves Tianyi and that Tianyi loves him back. Ling's love for him then grew into hatred. She started to scheme and build traps to make them look like they hate each other, which led them to become desperate for each other's love. This song made it clear that Ling was one of the main reasons why Tianyi stabbed YANHE in the first song: "Shuāngxiàng Sīniàn".

After Ling received her own voicebank in 2015, her vocals were used to sing the song in the album Shuāngxiàng·Lúnhuí yǔ Xìngfú.
