SC text + lots of beauties + blackening (although I have no love for blackening) + one-on-one ending.
I can't think of a copywriting yet, I'll make it up later!
PS: Yameng will always be the heroine, the heroine is the heroine, and it will never change! Because the preface is a prelude to the female supporting character, this female supporting character is more important and it would not be possible without her, so this female supporting character was written in the preface. But guys, don't worry, you won't abuse the heroine, so you can continue watching with confidence!
