Idk why she's crying either but trying to make up for dramatic manhua writing with "she's human" is like trying to excuse your dog for eating your homework cuz it's a dog lol
Things will only tell in the later chapters (including them disclosing their private issues that they hide from each other, and the reason why she's crying). The drama is drawn out af, but if the writing isn't bad, it should all be explained, whether it's in 6 chapters or 60 chapters.
Thanks for the chapter!
