He might be a sakura.

It's the best season for 桜 (sakura, cherry blossoms) now in Tokyo.

In this season, a lot of people drink and eat under sakura trees in the park or river side.
It's getting warm but still quite cold outside especially in the evening, but people try to drink in the park with coat and scarf. (^ ^;)

The event is called 花見 (hanami).
(Just in case... 花見 (hanami) is seeing cherry blossoms and 花火 (hanabi) is fireworks.)
I did hanami last weekend with my friends, too.
Do you have similar event in your country?
Do you sometimes drink outside even if it's cold!?

By the way, there is another meaning for the word "Sakura".
Another sakura is usually written in katakana and describes people.
When people are trying to sell something, if there isn't any customer, people usually don't care about the shop.
But if there are many customers, you could be interested in the shop.
So shops sometimes hire people who pretend customers.
The people are called サクラ (sakura).
They are called sakura because sakura trees seem very gorgeous and the flowers fall soon.
The people try to do same thing.

The way of using the word "sakura" is popular in Japanese.
Try to use the word when you talk with your Japanese friends.
Like...
"Wow! That store is very crowded!"
"Well... maybe some of them are sakura, don't you think so?"
