——"Wen Yi, you are my protagonist."
Wen Yi was forced to travel through time and bound to an unreliable "strategy system"; Mu Yayu secretly followed Wen Yi through time due to some force majeure events. In order to change Wen Yi's cannon fodder fate, Mu Yayu had to bind the "points system" to change Wen Yi's cannon fodder fate.
"Yiyi, can you please leave your target alone!"
The dull and slow junior sister (Wen Yi) & the gentle and protective senior sister (Mu Yayu)
(Wen Yi doesn't know that Mu Yayu has also traveled through time; there is a layer of fate between the two people in the current world)
Intention: self-respect, self-love, freedom
