∑(*ºㅿº* ).ᐟ.ᐟ

Two asterisks sit up high in this face, at about the same height as the eyes: one between the opening parenthesis and the left eye, the other just to the right of the right eye. They can read as flushed cheeks. The eyes are a pair of º, MASCULINE ORDINAL INDICATOR, the small raised o that Spanish and Portuguese put after a number to make an ordinal, as in 1.º. Lower than the eyes, around the middle of the line, sits the mouth, ㅿ: a hollow triangle with its point at the top. Unicode names it HANGUL LETTER PANSIOS, a letter of old Korean that modern Korean spelling no longer uses. It's a full-width character, so it comes with a margin on each side, and although no space separates it from the eyes, the face doesn't look cramped. Round eyes over a small, pinched triangle of a mouth: someone who has just let out a short "oh!". The only space in the face is the one between the right asterisk and the closing parenthesis; on the left, ∑(*º runs on with no space at all. Surprise marks bracket the face on both sides. On the left is ∑, a mark much taller than the eyes. Kaomoji place it beside a face, as in ∑(ﾟДﾟ), to show a startled jolt. It looks like the Greek capital Σ, but this one is N-ARY SUMMATION, the summation sign from math. On the right, straight after the closing parenthesis, .ᐟ.ᐟ does the job of a "!!". On X, someone posted it right after がこおつ〜, a clipped, casual Japanese greeting for someone who's just done with school for the day, so it also works as a loud, cheerful hello, not just a face for real shock.
