By some twist of fate, the protagonist encounters their destined soulmate of the same gender and, as expected, falls in love with her. However, even until now, they have not lost their feelings for their precious, beloved fiancée whom they have loved together. The destined soulmate and the fiancée clash fiercely with the protagonist caught in the middle. So which way will the future go for these three people? I am also posting this on Alphapolis.
