The third-to-last scumbag suddenly counterattacked and became the place that the famous universities competed for. The teachers and students of the school were in an uproar…

Others are busy studying, Shen Mianmian is busy doing small business to make money…

Others were preparing for the college entrance examination, but Shen Mianmian bought the two most famous haunted houses in Kyoto in one go… She became an outlier in the eyes of everyone, laughing at her if she bought it with life, but not necessarily with life.

Others were busy looking for jobs after graduation, but the haunted house purchased by Shen Mianmian was expropriated by the government and received a considerable amount of demolition money.

The person who once laughed at her couldn’t help but slapped herself… I asked around where there were still haunted houses for sale.
