A disaster causes three people to travel through time. Where do they end up? In desperation, once you enter the world of mortals, where will your love go? Gratitudes and grudges in the rivers and lakes, battles of wits in the palace, can only keep life safe. In this life, there is only one dream, and I am afraid that I will fall deeply in love and be unable to extricate myself. If you can't have both love and friendship, how should you choose? How can I make myself feel at ease without regrets!
