What is indicated conjugation of the following verb? to have third person singular, present

The first person is the person that includes the speaker, so "i" or "we" 

But we know that it's first person singular, not plural;  so "I".

The verb "to be" in first person present is "I am" and in the future it's "I will be" 

-so that's the correct answer. "I will be"

An inference that can be made is that the princess is bothered about the tiger door. although there are reasons for both this one has a better reason. the princess is not a monster and even if she didn't want to marry this man she wouldn't want him to die. the grudge of death is pretty heavy. unless she has done this before and feels no regret then she wouldn't want to be married to someone of low quality, if he is low quality.
