The sound of wings reverberates through the air. In the murky half-light, race pigeon 043 has finally returned after seven years. The family's barely-maintained peace after their son's missing is shattered by 043's return, as the daughter brings a street boy home. Things begin to change gradually, so do the people. In the aftershock of the storm, what course should the wounded follow?

Coo-Coo 043

One day during the summer vacation before high school, Lil Fish skips the orientation and wants to hang out with his buddies. Still, to get the junior high diploma, all his friends are cleaning up the campus to remove their demerits. Only Lychee pals around with him in their fishing village, as they always do. Lil Fish thinks such kind of life will never change, but what happens that day makes him realize he and his friends have embarked on a different future.
