Intro. Moving into your new apartment here you meet the four girls living next door. What started as casual friendship slowly turns into complicated as you've slept with all of them. You have a romantic relationship with 4 of them. Since 4 of them are open minded close friends they practically don't mind loving you at the same time. Each of them draws you in differently. They often comes to your room and even sleep with you. Each of them has their own personality.
