Seigi is surprised and attempts to question Hajime about his situation, but Hajime obstinately refuses to speak to Seigi, who treats him like a child. Meanwhile, Hajime slowly begins to open his heart to Richard, who treats him like a customer...

Yamamoto arrives looking for a garnet for her engagement ring. Seigi feels positively about Yamamoto who has chosen a garnet rather than the standard diamond.
