Briss

An intense, soul-deep yearning for someone you love deeply that surpasses the boundaries of a typical "miss".
Derived from the words Brick and Miss (exact origin remains unknown)
Briss describes a complex state where one experiences a deep sense of longing and nostalgia, yet continues to perform their daily responsibilities and obligations.
