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...
When things aren't going well 
for me or my head feels foggy,
حينما تكون الأمور لا تسري 
،بخير بالنّسبة لي أو أنّي محتارة
Wenn ich etwas nicht richtig formulieren kann
oder ich mir über etwas unsicher bin,
Cuando nada me sale bien
o me siento mal,
Cuando las cosas no me van bien
o me siento mal,
Quand les choses ne se passent pas bien
ou quand je suis perdue,
Quando le cose non vanno bene o mi sento confusa,
Quando as coisas não dão certo para mim
ou quando minha cabeça está enevoada,
Когда у меня что-то
не ладится или путаются мысли,
