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...
Just that a genuinely bad person 
wouldn't bother telling me that.
فقط أنّ شخصًا طالحًا حقًّا 
.ما كان ليخبرني بهذا
Nun, eine wirklich böse Person
würde das wohl nicht extra sagen, oder?
Alguien malo
no se molestaría en decirme eso.
Alguien malintencionado
no se molestaría en decirme eso.
Un malfaiteur
ne prendrait pas la peine de dire ça.
Qualcuno di davvero cattivo non si sarebbe
preso la briga di dirmi una cosa simile.
Alguém que realmente é mal intencionado
não iria dizer essas coisas.
Согласитесь, настоящий мошенник
не стал бы так говорить.
