Aggressive Retsuko (ONA) 4th Season

After leaving her brief idol career behind, Retsuko tries to return to a quieter life while her hesitant relationship with Haida finally begins moving forward. Then a new company president imposes severe reforms and gives Haida the responsibility and recognition he has always wanted. The promotion offers him a chance to prove himself, but it also pulls him into decisions that no longer resemble the person Retsuko thought she knew, especially when suspicious accounting practices appear and longtime employees start losing their places. Loud music can release anger, but it cannot restore trust. If Retsuko wants to save what exists between them, she must confront Haida before his fear of failure gives him a real reason to lose everything.
