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...
Maybe that's how love works, 
but I think marriage is different.
،ربّما هكذا يسري الحبّ
.لكن أظنّ أنّ الزّواج مختلف
Das mag bei Liebschaften zwar so sein,
Tal vez así funcione el romance,
pero el matrimonio es diferente.
Tal vez así funcione el romance,
pero el matrimonio es diferente.
Peut-être bien en amour,
mais le mariage, c’est autre chose.
Forse per l'innamorarsi funziona così,
ma penso che per i matrimoni sia diverso.
Talvez seja como o amor funcione,
mas acho que se casar é diferente.
Может, в любви всё и так,
но брак — другое дело.
