If the current youth of the post-00s generation is characterized by the exciting battles on Summoner's Rift, the completion of military bases, or the crazy pursuit of idols in the entertainment industry, then we, the empty-nesters born in the 90s, have long been far away from them. I grew up reading Taoist theory. Although I was born in the 90s, my heart has always longed for the life of a veteran cadre, where fishermen sing into the evening, lonely wild geese, and the vast world. The term youth is already far away for me, but I still occasionally think of running under the sunset that day. It was my lost youth. "Little sister" is one of the more popular terms nowadays. The short humorous idol inspirational story I wrote for the first time is also related to little sister.
