This is actually a simple story.
Two men and a woman, a story about love.
Although it is told from the perspective of the heroine most of the time, what it wants to talk about is the love between people, between men and women, or between men and men.
That's why I hesitated and classified it into the Danmei category.
Although I don't want to admit it, it is indeed about the seven-year love-hate relationship between a straight woman and a pair of gay friends. . .
