The narrative-driven gameplay revolves around reading through the story and making choices that determine the character routes. The choice system is straightforward, with relatively simple and obvious options that allow players to easily navigate to their desired storyline.
The sequel features a longer and more developed story compared to the first installment, with four main routes corresponding to the four heroines - Ciel, Koron, Rira, and Richer. Each route offers a unique perspective and character arc, allowing players to explore the lives and relationships of the cast in depth. Reviewers praised the developers for crafting natural, well-paced character development and conflicts that avoid feeling forced or contrived. Additionally, the game includes shorter "after-story" segments that continue the narratives of Rira and Richer from the previous title. These branching paths provide a satisfying conclusion to their storylines and give players more time to spend with the beloved characters.
The visual novel's user interface is described as simple and straightforward, enabling players to easily navigate the story and access features like the save/load system, music gallery, and character CG gallery. The game supports multiple language options, including English, Traditional Chinese, and Japanese, making it accessible to a wider audience.
