Differences between Korean and English versions
The English-language version of Maybe Happy Ending largely follows the same plot as the Korean version, with the removal and addition of several characters and songs. In the Korean version, Oliver is a Helperbot-5 and Claire is a Helperbot-6. Characters in the Korean version that were cut are Oliver's mailman, whose aging during "World Within My Room" signifies the passage of time, and Claire's friend John, a fellow Helperbot-6 who visits to help fix her charger. Gil Brentley is an expanded version of the nameless spectral jazz singer in the Korean version, where he is part of the James/Multi-man role. James' son Junseo is new in the English version; in the Korean version, Oliver's interaction with James' family takes place offstage during the song "What I Learned from People". Claire's owners Jiyeon and Suhan, portrayed in a pre-recorded video, are absent from the Korean version, where their relationship is portrayed via a duet between the onstage band's violinist and cellist. The English version adds a subplot about Helperbots' administrative passwords; in the Korean version, Claire and Oliver are able to erase their memories without a password. In the Korean version, there is a subplot involving a clasp that Oliver makes for Claire as an adapter for his charger; in the final scene Oliver gives it to Claire after it is revealed that he kept his memories. The English version runs about 10 minutes shorter than the Korean version, cutting the scene and song "Nevertheless" (그럼에도 불구하고), which explicitly depicts Claire breaking down and Oliver's attempts to repair her.
