Aries Allred, a 20-year-old man living in Tokyo Japan attending Mizuki Institution, has a very hard time attracting others. Due to a traumatic experience as a child, he has lost the ability to show his emotions and connect with/trust others. The only person he has left is his siter Aiko. During his 1st year in college, he meets an upperclassman, Nitta Minori, a rather aggressive girl who doesn’t take no for an answer. After a coincidental encounter between the two, Aries’ calm boring life begins to flip upside down as he slowly comes to learn to love and trust again.
