why "懐かしい"?

"懐かしい" (natsu-ka-shi-i) is a Japanese word that describes a feeling of nostalgic longing, often felt when thinking about someone or something from the past. It’s held a special place in my heart since the beginning of my creative journey, as it was the username of my very first creative account (@nnatsukashii). Over time, it’s grown into something more than a name. It reminds me to move forward while staying connected to the memories and moments that shaped me.
