Four more days passed and the propeller was finally finished. After installing it, the Aquaterrans test the ship to make sure it will work well and they won't have any problems in the future.
Elder Jin suggests a feast on the previous night of Astri's group leaves. At the same time, it's a happy moment that they can leave, but they also feel a little reluctant to go because they know they will stay on the ship for very long days.
Astri sits between Claud and Elder Jin, listening to Elder Jin's stories and then Koa stands up to go outside.
"Is Koa all right? He feels gloomy." Astri asks Jin.
"Oh.. Don't worry. He's like this because you're leaving." Jin answers.
"I see… Let me talk to him." Astri says.
Astri stands up and walks outside to find Koa watching the stars. She also taught him about the constellations and now every night he looks at the stars.
"This seat taken?" She asks, pointing to his side.
He chuckles.
