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...
I felt as though someone had 
opened the door to my cage.
.شعرتُ وكأنّ أحدهم فتح باب قفصي
Es kam mir so vor, als hätte jemand
die Tür meines Käfigs geöffnet.
Sentía que alguien había abierto
la puerta de mi jaula.
Sentía que alguien había abierto
la puerta de mi jaula.
J’ai eu l’impression
que quelqu’un avait ouvert ma cage.
Mi sentii come se qualcuno
avesse aperto la porta della mia gabbia.
Senti que alguém havia aberto
a porta de minha gaiola.
Мне показалось,
словно кто-то открыл мою клетку.
