I did not know that Japan had such a thing where you would give chocolate to another and then give back the next month. I think that it should be more just like in the US where we can buy any gift to show that appreciation or love to that significant.
I believe that media plays a big part in shaping the world or societies today. I mean the business are getting lots of money that this is how you should love. I think that creating such things for businesses may in turn hide what love really is. I believe that we need love everyday and not just that time of the year like V-day and so on.
If I were an international student in Japan, I would make relationships with others and spend time learning and helping those individuals as much as I care about myself. I would treat them how i would treat myself or my family.
