Still, I Want to Make You Happy

Plot Synopsis

Returning to his hometown for high school after nine years away, Fukutome Kouya is thrilled to be in the same class as his childhood friend and longtime crush, Koutomi Manaki. The two had kept in touch daily despite the long distance, and he's resolved himself to finally confess to her on the first day of school. But when he finally decides to make his move, Manaki suddenly faints, only to wake back up acting strangely different - and only then does Kouya realize that his other childhood friend Tamaki, who he thought was an entirely different person, was actually Manaki's other half. On top of that, while Manaki wholeheartedly accepts his confession, Tamaki adamantly refuses, and Manaki faints and switches out at the slightest sign of affection! With Tamaki's help as wingman, can Kouya successfully overcome Manaki's inability to handle romance?

How is it plural?

Manaki and Tamaki are explicitly stated to be "split personalities" and formed in a manner similar to a DID system, and the story revolves around the difficulties caused by dating one alter in a system but not the other. The series' otherwise surprisingly accurate portrayal of systemhood is unfortunately somewhat undercut by the reason for Tamaki's formation being not trauma, but excessive doting from their parents that led Manaki to feel like she was going to "die of happiness"; looking past the comical approach to their formation, however, the series is a rare gem in terms of portraying systemhood as something that has difficulties, but is not necessarily only bad and can even be a blessing under the right circumstances.
