Where should the four sisters Gu Ruohan, Mu Tingjun, Geng Ranlin, and Han Feiya go? Can they recognize each other, can they eliminate dissidents, can they fight the enemy together, can they solve the puzzles of one world after another, can they find their original intention, can they find true love, can they untie their knots and face all the truth.
Intention: Don't be suspicious of besties or love.
