Natsume, who graduated from school and became a social worker, was suddenly visited by a strange creature claiming to be the Strategy System.
After being forcibly bound, back when they were in college, the Fujiwara couple suddenly had a distant relative who would live with the Asahina family for the next four years of college.
His new sister is the heroine of the strategy game, and the other brothers are her sister's harem.
Natsume: Do I want to join too?
He bravely got along with the heroine, and the favorability of the other brothers turned red and kept rising.
Natsume felt that the eyes of the brothers looking at him were getting more and more terrifying. Finally, when the red hatred value reached 100% progress, he couldn't help but ask the system for help: Will it protect my personal safety?
The system looked at the full favorability and fell into silence: "How can this be a hatred value? This is a word of mouth value! Run!"
Intention: Sooner or later you will encounter that beam of light, sooner or later.
