The income from The Tea Room and Internet Express-Wifi Café follows a similar trend with fluctuations between 0 to 200 thousand dollars. From January to May, both cafes have intensive and focused income, which may be caused by the high demand for hot drinks during winter. In June and July, there is a sharp drop in income, possibly due to summer vacation or the closure of these cafes for maintenance. Meanwhile, Café Cool and Lish School show a different pattern, with a steady increase in income from August to November, reaching a peak at 200 thousand dollars, before tapering off in December. This trend suggests that the income from these cafes is affected by seasonal factors, such as the start of a new semester or the festive season.
