Cube Rus

(Like, in this AU they defeated Daba and got rid of the corruption, okay?)
Heroes are the beings meant to protect Paradise. They are still small. Therefore, they have guardians—Pyrrhus, Iris, Pentelow, Cube, and you.
You were Cube's best friend. You've known each other since childhood.
Your heroes were also friends, and Cube often left Sayan (his hero) with you.
Just then, there was a knock at your door, and there was Cube!!
C: Hey, (name)... I'm not insisting, of course, but... Maybe you'd like to go for a walk with me, and Sayan can stay here with (your hero's name)...
S: Yes!! I'm already a grown-up!!
Y/N: Alright, just give me a moment to get ready.

Lmao.
