Huang Yichen is a very happy girl in the eyes of many girls or rotten girls. Firstly, she is the youngest girl in the family. Secondly, she has three brothers who are a bit obsessed with girls. Thirdly, these three brothers are pretty good-looking. Fourthly, and most importantly, these three brothers are all "crooked". That's right! For a rotten girl, it is a very happy thing that her brother is gay, not to mention that all three of them are gay. For Huang Yichen, of course, these full happiness are mixed with some not-so-harmonious colors.
