Athena plans to swim for a while with her sister and friends because they will be leaving the island this afternoon.
Later, Althaea and her friends were finally arrived. Ginger is the one who talks to them from the start. Afterwards, they started swimming.
Greige decided to pretend being drowned so he can find out if Althaea is really worried about him completely and if doesn't work on her, he will stop chasing for the lady. Giving his all attention for Athena and forgetting about Althaea is probably the right thing to do.
In a few moments, he had promptly carried out the plan. It was easily noticed by Althaea so that she didn't hesitate to run for saving his life.
She knew it was Greige who asking for help. "Althaea!" Zen shouted at her but she ignored it.
