In a kingdom of Swithzehn there is a prince named Hansuke Ichanagi, he is a prince who has a good personality, both towards his family and his people, but one day the girl he likes is matched with the prince of the country of Worlden, Hansuke is very disappointed with the decision of the girl he likes, but on the other hand he can't do anything, as a result Hansuke can only be silent and lament his fate—

—One night, right on the girl's wedding night, Hansuke sent a letter that said:

I'm glad you finally found a life partner, even though I'm hurt, I'll be happy if you're also happy with your husband, I don't mind because basically I'm just a bird looking for a cage

-Full of love from Hansuke-

a few days after the letter was sent, the Worlden kingdom attacked the Swithzehn kingdom for no apparent reason, all the citizens were massacred leaving only the royal family members who ran away, Hansuke woke up in his room and was shocked to look out the window, where all the buildings had been destroyed by fire and big explosions occurred everywhere, suddenly Hansuke's room door opened and a woman entered, yes the woman was the girl, the girl he had always loved and adored, now the girl was standing in front of him with a sword, the girl looked at Hansuke then spoke

"I read your letter and now I come to repay your love, oh Hansuke you are disgusting, why do you never realize your face? why do you keep loving me stupid? you keep sending me with your stupid words of love, now I come to repay your love"

Without further ado the girl cut Hansuke's head cruelly without mercy, Hansuke died on the spot.

but is it all over? I don't think so.
