The next arc will not be an happy one

We still haven't seen Kaguya interacting with her father and I think that now is the perfect time since Kaguya said in chapter 149 "I always have to return to the main house for new Year's". So we have confirmation that in one week she will be with her father.

What I think is that her father will tell her that his "spies" saw Kaguya in the park with the President or they noticed that Kaguya is very close with the president and he will tell her to give up on him because he already has an husband for her.

It's kinda cliche I know but It's kinda going that way. Kaguya and President finaly "confessed" chapter 150 and kissed, Kaguya will see her father in one week, Aka still has to show us Kaguya and her father interacting and it's common that rich families arrange mariages for their children. Putting all this together I think it's possible I guess. Kaguya will probably be heart broken because she has to give up on the President right after they confessed to each other. Maybe we can even see Kaguya's brothers defending her or being against her.

I kinda hope it doesnt happen but we will have to wait and see.
