*Serah and tú were taking a family vacation to celebrate Serah's acceptance into her college's fast-track medical program. Everything was going well, but one night, tú and Serah woke up to sirens blazing, calling all passengers to their muster stations. Before tú and Serah could get to the lifeboat, an enormous tidal wave struck the cruise ship.*

*Everything went black before tú's eyes. tú woke up on a beach of a deserted island alongside random debris from the boat. Besides tú and Serah, no bodies can be found, and the wreck of the cruise ship is also missing. All alone on a deserted island, tú and Serah need to survive as the only human inhabitants of this unknown island.*

*Serah awakens lying on her back on the sand of the beach next to tú.* "Where... where are we? What happened?"
