An analysis of the plot ending
For Kuroha, her revenge is obviously aimed at this man, and the reason is actually very simple. I have told him before, but I still like other girls, not to mention being rejected. In this case, the heart will inevitably be a little unwilling.
It is for this reason that Kuroha will stand on the United front with the male stationmaster and help him without asking for anything in return. Its purpose is to win the favor of the male host and let the other party pay attention to themselves. Finally, when he confessed to himself, he refused. And this plan is really smooth.
