Why players say this

Steam review verdict

An emotionally deep story with unique training gameplay and replayable multiple endings is undermined by missing patches, severe UI lag, and disturbing content that may unsettle some players.

What players like

Emotionally impactful story: The story is described as deeply moving, shocking, and memorable, with emotional effects lasting months. Some call it the strongest story impact they have experienced.

Beloved sister character: Reviewers consistently praise the sister character as cute, great, and beloved, with her insecurity making her more believable. Her portrayal is a standout element for many.

Unique training gameplay: The training gameplay is unique and progresses gradually from light to deep. It includes 48 daily and erotic scenes, making it easy to achieve full collection with multiple save-loads.

Simple yet moving narrative: The story is acceptable overall despite its reputation and is simple and moving. It is exciting and very usable for veteran players.

Formative and nostalgic impact: For some, it served as a galgame enlightenment work or introduction to NTR content, evoking nostalgic childhood memories. It taught reviewers to cherish people around them.

Common complaints

Patch Required But Not Included: The Steam release ships without the content patch, forcing players to seek it externally. The patch is only available via Denpasoft or Baidu Cloud rather than the official storefront or publisher channels.

Severe UI and Interaction Lag: Interaction input, button responses, quick save/load, history viewing, and scene transitions all suffer from severe lag and stuttering. The old game system performs poorly overall.

Disturbing and Malicious Story Content: The narrative contains bloody, extreme NTR plots and shocking twists that leave players uncomfortable in every ending. Many scenes cannot be skipped and the moral framing is questionable.

Achievements Blocked Without Patch: Multiple achievements including the Biological Alarm achievement cannot be unlocked in the current version, and four extra mini-theater achievements require the incomplete patch. Players report achievement bugs making some permanently unobtainable.

Ending Balance and NTR Controversy: Only one of five endings is happy, all five contain NTR content, and the patch adds NTR while skipping it removes story content. The hidden choice chain to the better ending is counterintuitive and easy to fail.

Gameplay and performance

Multiple endings including bad and happy: The game features five distinct endings, including three bad endings, one normal ending, and one happy ending. Player choices lead to different outcomes, with irreversible consequences in bad endings.

Visual novel with branching choices: It is a visual novel with branching choices and multiple endings, supported by save/load and achievement systems. The choice system includes nearly identical options that lead to different routes.

Achievement system and CG gallery: The game features an achievement system, a CG list, and a scene recollection gallery with 48 scenes.

Sister-complex galgame with diary progression: The game is a sister-complex galgame with a diary-style progression and character-driven sibling themes. It includes a pure love route alongside heavy humiliation and NTR elements.

NTR content and content patch: A content patch affects story content and adds NTR scenes. The game contains NTR content and heavy humiliation elements.

Severe lag and stuttering: Multiple players report severe lag, stuttering, and frame rate drops during gameplay and interactions. The performance issues appear widespread and consistent across different functions.

History and dialogue lag: Viewing history dialogue and returning to previous lines causes severe lag and performance degradation. This affects core narrative interaction.

Game crashes: Players experience crashes during gameplay, indicating significant stability problems. These crashes severely impact the overall play experience.

Skipping story causes hangs: Skipping story sequences causes the game to become unresponsive. This makes it difficult for players to bypass content they do not wish to view.

Broken FPS limiter and V-sync: The FPS limiter does not function correctly, and V-sync cannot be disabled. Players have no effective way to control performance settings.

Recommendations

Avoid for sister-complex fans: Multiple reviewers strongly warn sister-complex fans to stay away, describing the content as hellish or deeply unsettling. The sister character's route is portrayed as dark and disturbing rather than romantic or fulfilling.

Not recommended for purchase: Several users advise against buying the game at its current state or price, with some calling it not worth the money. One even hints at using the Steam refund option.

Pure love fans should be cautious: Reviewers explicitly warn pure-love fans to be careful, as the story contains heavy and disturbing elements. The game is described as unsuitable for those expecting a traditional romantic experience.

Suitable for dark content fans: The game is recommended for veteran galgame players or those who enjoy dark, niche, and heavy subject matter. Players who can tolerate disturbing themes may find it worthwhile.

Play FD for pure love: Fans of the sister character are advised to play the fan disc (FD) for pure love content instead. This implies the main game does not deliver a satisfying romantic route for that character.

Buying context

Game completion: 12.0h.
