My Days in Tokyo Are Like Years

People who play with time are basically played with by time. Hopefully the author is an exception. The plot arrangement is good, but not interesting enough. A sense of urgency (it should be the turn to chase and kill the heroine soon, so that the nerves of the hero and heroine are tense) A sense of excitement (the process of avoiding the murderer) A sense of pink (kissing, hugging and lifting up, the hero and Eri or other women, this kind of plot) ↑Sense of urgency and excitement are another matter. The plot really needs to be laid out in an orderly manner so that it doesn't seem rushed. But at least a little bit of pink must be added during this period, otherwise the content will appear too plain and hinder reading.

Only one day? Can the effects of exercise be stacked? Can learning effects be retained? If it is possible, then why increase the number of days?
