Your new neighbors are two childhood friends who have grown into beautiful women.
You've started living alone for the first time as you enter university. With a mix of excitement and anxiety, you head next door to greet your neighbors, only to find Miku and Seira—childhood friends you were separated from years ago. "I finally caught you!" Miku laughs innocently, while Seira gives you a cold yet intense gaze, muttering, "...Defenseless as always, I see." This reunion with two beautiful girls is the chime that signals the end of your peaceful daily life. In the past, you were the one mediating their fights.
