I bet her father went rampage and destroyed the imperial family and that coward emperor. Seems like he act that way to make sure she wont be the target, even that emperor threaten him using his daughter. Bet that sword was for her safety but she misinterpret it.. Hmm, mostly they show the first timeline in sidestory.
he went crazy and killed the emperor since his daughter is the only reason why he is still living.. his daughter is his purpose of living and her dying probably affected him mentally
That's what I think too
We only saw her version...maybe "endure it" meant hang in there till he saved her
Poor guy is just bad at communicating(￣∇￣")
Tbh I'm really curious what happened to her father and the prince after she stabbed herself in the past. ╥﹏╥
