Ruu no Rakuen

Ruu’s favorite place is the aquarium where her father works, a home she shares with its staff and animals. When she overhears that the aquarium is going bankrupt and may soon close, she is determined to save the sanctuary she loves. Ruu turns to Ichinose Sena, the wealthy heir to the Ichinose Group, for help. Sena treats her coldly and suspects she is interested in him only for his money—and he may not be entirely mistaken.
