Anna: You should definitely mention the main characters in the book in the summary and evaluation but no need to mention them separately from those.
Mitsu: I'm shocked that you are still alive! No one I know (relatives, close family, friends) has drunk Coca Cola in twenty or thirty years--- much less doing ikinomi with it. It has nothing good in it. The original "lift" in it was from cocaine ("coca plant"). Now---cocaine having become an illegal substance---it is high fructose corn sugar (the ubiquitous ingredient in almost all American processed foods that makes them obese), caffeine, and a variety of acids and chemicals. It is so toxic and acidic that farmers in India use it as cheaper way to kill insects on their crops! Literally, you are destroying your health every time you take a drink. I recommend that you avoid Coca-Cola like the plague if you have any hope of reaching thirty . . . Please take care of your body while you are young so that you can have a long and healthy life later.
