Tutor fan, Demon X Giotto.
In the original work, Xiang is considered be, after all, they have never been together.
If I had to classify them, they would be Gong, who is stubborn and stubborn to death, and Shou, who is tolerant of everything and sees through things without saying anything.
Demining: Demon can't let go of his ex-girlfriend, Giotto will marry a wife and have children, but they have feelings for each other, and they don't have the plain and watery feelings of adults who are together. There will be no cheating plot, at most Giotto will be kissed by Demon before he meets his wife. Update slowly, quite slowly.
Intention: It is love but also cowardice.
