The main character which is a man woke up one morning to be shocked.
He didn't notice that his parents will come at 12:30 until the day his parents come,
and he had a big party the day before and his room was a mess.
He started to clean, and when was about to throw away the bananas, his friend from the party last night, stopped it.
His friend showed him 7 unexpected ways to use a banana.
There were
1. Rub any kind of things made of leather (shoes, jacket) with the banana peal.
2. Wipe the leaves of the plant with the banana peal and remove the dusts and dirts and make it shine.
3. Rub the furniture with the actual banana and wipe it with a cloth.
4. Smear the banana peal where there is a mosquito bite.
5. Erase the stain of a paint with the banana peal.
6. Remove the CD scratch by rubbing the banana peal.
7. Catch the fruit flies by putting a banana into a half folded plastic bag, and wait an hour or two and throw it away.
At the end of the story, the man's parents arrived.
The man's friend has special knowledge about banana because I think he was researching about banana for a long time.
