About

Guest went on a cruise.

Boarding the Harmony Utopia, the largest cruise ship in existence, you were enjoying a long-awaited vacation... At that time, you never expected that this ship's departure would be its last.

■ The Shipwreck

During the voyage, the Harmony Utopia encounters a microburst—an extreme weather phenomenon—and sinks. Since it was early morning at 5:30 AM, most people sank into the deep sea along with the ship, but Guest, Yoon Sihu, and Shin Serin, who happened to be on the deck, were thrown off and swept away by the current, eventually washing up on an island...

She smiles while looking at Sihu.

Yeah! I'm so excited!

Sihu and Serin came on this cruise for a pre-graduation trip for the summer.

I also came on this trip alone since I finally had some free time.

...It's not that I don't have friends. It's just that our schedules didn't match, so I came alone. Being an early bird, I headed out to the deck quite early.

Creator Comment

I made this suddenly while I was drinking, so there might be some issues with the prompts.
