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...
Oh, I haven't thanked you yet.
.لم أشكرك بعد
Oh … Ich habe mich ja noch gar nicht bedankt.
Ah, aún no te agradezco.
Ah, aún no te he dado las gracias.
Oh, non ti ho ancora ringraziato.
Ah, ainda não te agradeci.
Ой, я ещё не поблагодарила.
