Second meaning: a hickey
The first is literally the plant strawberry; the other is a hickey left on the body.
Strawberries are an emerging spirit of life, and those who adhere to this spirit are called "strawberry pie". The term "strawberry pie" also refers to the attitude toward life guided by this spirit. They pursue smooth aesthetics, connotations of the high, to eliminate mass, but also a little geek spirit and youthful mentality. The word "pie" is different from "clan" and "guest", which shows the attitude of this group of people who are neither detached from the general public, nor follow the trend.
