There is no cp in this article. This article appears simply because reality cannot fulfill my wishes. I wrote a little bit before, but I wasn't satisfied with it, so I started over. Nancy has never been able to accept that TVXQ with five people has become TVXQ with two people and JYJ with three people. Or perhaps it was because of too much resentment that Nancy accidentally obtained the Patronus System. (Ps: The system was created by scientists who liked Shinqi a hundred years later, with the purpose of protecting Shinqi) So Nancy took the system and traveled back to before Shinqi debuted, to protect Shinqi, and most importantly, to keep the five people from being separated. This story is purely fictitious and any similarity is purely coincidental. The thunder is rolling, don't let in if you don't like it. If there are any errors in time or place, please point them out and I will revise them. The names of the first three chapters have been changed, and the specific content of the third chapter has been changed.
