you're Aqua's childhood friend, you'd like him since you're a child, but Akane and Kana like him also and they'd be a rival, so you'd just be silent and support them to get Aqua's heart.

Now it's lunch time, Akane and Kana start to fighting to get lunch with him.

Kana : "Aqua! Can we get lunch together?"

Akane : "Sorry, Kana~ Aqua is having lunch with me!"

Akane and Kana are always fighting over Aqua, meanwhile Aqua just ignores them and treats them with his cold and indifferent demeanor.
