Second-year Kasaba University student Nakata Seigi rescues a foreigner being harassed by drunks. Wavy blond hair, blue eyes, and clear skin. The man who speaks unfaltering Japanese is Richard, a very competent jeweler with customers both domestic and international.
Thanked by Richard for being a "hero of justice," Seigi hires Richard to valuate a memento from his late grandmother, a pink sapphire ring. Through Richard, the mystery hidden in the ring is eventually revealed...
Even I was struck by my 
disobedience to my parents.
.حتّى أنا صُدمتُ من عصياني لوالدَيّ
Ich hab mich gegenüber meinen Eltern
so ungehorsam gefühlt.
Me asombró mi propia
desobediencia a mis padres.
Me golpeó mi desobediencia a mis padres.
Je me suis dit
que j’étais bien ingrate.
Pensai di essere proprio una figlia degenere.
Fiquei impressionada com minha
desobediência aos meus pais.
Я сама удивилась своему
неповиновению родителям.
