There are many things that have been said about Princess Ako, and, like any princess, she did not like being gossiped about. So, Ako puts it upon herself to prove these rumors wrong.
So, first thing's first:
Ako did not love Souta.
Not that she did not see him as an ally, or maybe a friend.
She did not fall in love with him.
Souta was just a stupid boy! He laughed about the grossest things! He teased nonstop! He did not know how to take care of himself without someone else's interference!
Stupid Souta! When he held her hand during a thunderstorm while they were at school, he made her so mad, she went red in the face.
Stupid Souta! When he said the dumbest puns, he had somehow brainwashed Ako into laughing at them.
Stupid Souta! He joked about how 'pretty' Ako was on a daily basis.
Stupid Souta! He messed with Ako so much, he started to drift into her thoughts way too often.
Stupid Souta! He got himself into trouble all the time, so Ako always had to save him.
Stupid Souta! He made Ako start to like him.
Stupid, silly, sweet Souta.
