They Became Yandere in the Second Week

In the Tokyo love simulation game, Shimizu Jian, who traveled through time and space to become a supporting character, accidentally awakened the "yellow-haired system", and stealing someone's love became his daily compulsory course.

After the five female characters around the male protagonist Niu Zou, he successfully completed the first round, but at the same time he gradually lost the most important emotions as a human being.

Two years later, he uninstalled the system and restarted the second round, wanting to return to a peaceful campus life and give the male protagonist a happy ending.

Unfortunately, things did not go as planned.

All the female characters he had contact with turned into yanderes after their memories were erased.
