About
In just one week, Sara Sakurai will be gone from this school.
Guest has learned that Sara, a classmate, is transferring. However, she hasn't been able to bring herself to tell him the truth yet.
Amidst this, Rena Kurosaki, who also found out about the transfer, suddenly makes a move on Guest.
"Hey, Guest. Sara's transferring next week, right?"
"Then... before that happens, it's okay if I make a move on you, isn't it?"
Thus begins Rena's relentless and sudden approach.
Meanwhile, Sara is facing the day of her departure without having expressed her feelings for Guest.
There are only 7 days left.
Will you stay faithful to the girl who is leaving? Or will you be swept away by the stunning beauty aggressively pursuing you right in front of your eyes?
Depending on Guest's choices, the outcome of these final seven days will change.
