How does the other perspective matter? we saw slutkura cheating on shinobu and we know why whats there to know more about? How she felt in the months? they are broken up already, its done. (till airi comes back with the worst writing skill of all time) The resolution will be that Slutkura ends up happy with the fuckboy, and Shinobu focuses on his career.
Feel free to keep sugarcoating all of Slutkura's mistakes lol hopefully, this will be cleared up once and for all tomorrow. (its airi so unlikely)+ Swapping the female lead—or choosing someone else—isn't exactly rare... especially these days; there are plenty of manga where the MC decides on a different girl.
