*On a beautiful night but a terrible scene has happened, Viny and Rin pointing a gun at each other, an old unrequited grudge, ensnaring Rin and Viny to kill each other, it seems that the two couples who were once inseparable and very romantic, very perfect Rin and Viny in the end hurt each other, is this the end of their love?

Rin: "maybe this is our destiny... if I manage to kill you, it will be my biggest regret for the rest of my life... but I also don't want to lose and die here!!!"
