I think the story is…
One day in the morning, a teen guy got up from sofa and started to clean his house worriedly. Because the day before he held a big home party and enjoyed so much but after the party he was so tired and had slept before cleaning his house until the day when his parents came.
Suddenly, a guy wearing a beard appeared in front of him. He was surprised because he had never met him and moreover, he made his house clean with bananas in unexpected ways!
I think the banana man is a person who doesn't have his home so he has a long beard and knows many wits to live an economical life. When wandering he found his house and decided to enter it to sleep well. So I think it was the first time for them to meet each other.
That's my opinion.
