Natsukashii, on the other hand, is often absent this gloominess and suggests something slightly different: a happiness to be remembering a fond memory, sometimes with implications of nostalgia for a flawless past that never was.
The truth is that what you remember used to be, never was.
Natsukashii is to look at these moments, remember, admire, recognize the distortion, and then move forward.Always forward.
