Can anyone tell me why ? It would be so interesting if the two had ended up together. Imagine, the main plot with the two deepening their relationship and Mc discovering more and more about the ghost. Why she tries to be a wingwoman, who she is and why she is linked to FMc.
For some subplot, it would be interesting to see Senpai falling in love, something simple, to not just be the main couple all the time and bring something new to the story. Or even a romance between Mc's friend and his sister (even if I'm not a fan of that idea)
But oh well, let's see what the author has planned and sorry for any mistakes, English is not my main language.
