Morisa's life-span theory refers to the tragic plot that a character CP with different length and life span dies before another in the works of Oriental Plan and its colleagues. Life-span theory also refers to people of different races falling in love, but because of different races and different life spans, they can only helplessly watch one party die, and usually end up being.

Of course, all this stems from the brain hole of the same person, which has spawned a number of works on longevity of the same person, making people who sprout CP inevitably more sad.

Theory of the origin of life

Although countless works have love stories with different natural lifetimes, such as man and demon, man and demon, etc. When it comes to the origin of life expectancy theory, we should also start from the fantasy land, that is, the old cult east of ACG. After all, the dream world has everything in this place.

In addition, orientals don't restrict the creation of colleagues, so a setting is always vague to facilitate the development of colleagues. Whether the theory of longevity is the groan of a fan creator with a big brain hole or the sincere feelings for CP, in short, as a teardrop, this article has been welcomed by many people, and it is painful and happy.
