When Seigi learns that his college classmate Tanimoto Shoko is going to a marriage meeting, Seigi is disheartened.
Seigi has some feelings for the gemstone-loving Shoko.
All he has left in his possession is a teardrop-shaped loose aquamarine he purchased from Richard that he intended to give to her.
Unable to say anything to Shoko, the discouraged Seigi returns to Etranger, where Richard gently encourages him by telling him to live without regrets.
However, behind his words is a part of Richard's past unknown to Seigi...
If you're still open by the time I'm done, 
I'll be back at mach speed.
،إن كنتَ لا تزال في المحلّ حينما أنتهي
.سأعود بأقصى سرعتي
Falls du noch offen hast, wenn ich fertig bin,
rase ich sofort zurück.
Si aún tienes abierto,
volveré a la velocidad del sonido.
Si aún tienes abierto,
volveré a la velocidad del sonido.
Si c’est réglé avant la fermeture,
je repasse vite fait.
Se quando avrò finito il negozio sarà ancora aperto,
tornerò alla velocità del suono.
Se me resolver dentro do horário de trabalho,
volto aqui na velocidade do som!
Если офис ещё будет открыт,
я мигом вернусь.
