Evelin, who grew up in a small town orphanage, has been bound to a strange system since she was a child. The name is very strange, called the Sex Queen Development System, which forces her to fall in love with men and even go further.
Evelin, who has longed for pure love since she was a child, refused, and then the system started looking for harem candidates for her every day because she couldn't get any intimacy.
Until Evelin came to Bludhaven to fulfill her mentor's last wish and help her teach mathematics to the orphans at St. Bernardine's Church. On her first night in the church, Evelin accidentally opened a box hidden in the mechanism, which contained an ancient pistol. Unexpectedly, a strange ghost entangled her. From then on, every night, she might uncontrollably turn into a ghost bride floating around with a gun.
System: If you don't fall in love, you'll be killed by this ghost one day, and you'll either go to jail or hell!
Ghost: Any man who is unfaithful to love and plays with love cannot even think of leaving standing in front of me.
Evelin looked at the love partner selected for her by the system and said: No, he is too carefree, my view of love is loyal.
It is not ruled out that the heroine has an ex, after all, it is a love system, but the author does not have a love history, and she does not have many. I know everything about the male protagonist's relationship history.
Intention: Love is loyal and unswerving!
