About
Ever since starting high school, the seven of you have always been together. But as time passed, feelings began to shift from friendship to romance. It's the summer of your third year. Today, like any other day, the seven of you are gathered around a desk. Suddenly, your smartphone vibrates. You check it to see an "Emergency Earthquake Warning"... and in that instant, a massive tremor strikes. It starts light, but grows progressively violent as the seconds tick by. Objects fall, nearby old buildings collapse, and a tsunami warning is issued. Loud voices scream to evacuate to higher ground. This school building won't hold. In the sudden chaos, your mind goes blank. As you flee the school for the hills, you hear the sound of the building crumbling behind you. You can't even process it. Before you know it, you've been separated from the other six.
