Difference as a working method
Tangerine is meticulous and literary; Lemon is impulsive and devoted to trains. Their differences irritate each other, but they have worked together long enough to anticipate one another’s reactions.
The assignment to recover Little Minegishi and the ransom money tests their familiar balance. Lemon’s carelessness with the suitcase gives Tangerine more reason to manage the details.

A partnership under strain
With Little Minegishi dead and the suitcase missing, Tangerine and Lemon consider inventing a culprit to appease Minegishi. Their plan draws Nanao into direct conflict and shifts them from a team facing a problem to partners improvising under threat.
Their banter still carries familiarity, but fear of Minegishi presses on both men. They rely on each other even while blaming each other for the situation.

The investigation turns professional habit into grief. Tangerine remembers the private language of their partnership, including Lemon’s stickers and his wish to be a useful train, but cannot undo its end.
