[Light novel + system + multiple heroines + healing]
Yamai Hiro, who travels through the parallel world of Tokyo, has awakened to the system since elementary school.
Determined to live a successful life, he later discovered that the system was only effective if he had sex with beautiful girls. What was even worse was that the bullshit system had cut off his lifespan at the age of 20.
Yamai Hiroshi, who had not met a beautiful girl recognized by the system for the first 19 years of his life, finally met his destined girl on a train in Tokyo.
So the boy who only has 7 days left to live has no choice but to hang out with the beautiful girl in order to survive (sad)
