About this game

What this game is, in the developer's words

"Pact between us" is a FMV. After the loss parents, you and your younger sister become siblings who only have each other. You must tenderly care for her daily life.What kind of woman will your sister grow into? Every arrangement you implement during her upbringing carries profound weight.

《Pact between us》is a life-simulation game featuring real actors.

​Synopsis:​
The story is heartwarming, focusing on a pair of siblings who suddenly lose their parents and grow up relying only on each other. After their parents' death, the older brother discovers he was adopted and has no blood relation to his younger sister. Despite this revelation, he chooses to raise her nonetheless.

​Addressing Controversy:​
It's unexpected that such a simple game would be labeled with the "LTP" tag and escalate into widespread online harassment. It's unclear who actually played the game before drawing these conclusions. ​​Our entire content promotes positive values​​, has undergone the platform's strict review process, and contains ​​absolutely no elements that guide or imply negative values for minors​​.

A child actor portrays the sister during her childhood stage, participating in various lessons and social practice activities.

As time progresses within the game and the sister grows up, she is portrayed by an adult actor.

Regarding the deliberate distortions and selective interpretations of what I referred to as an "emotional ending": This refers to the point in the game, ​​after the sister turns 18​​, where the brother chooses whether to reveal the truth of his origins. The "ending" then deals with ​​how the sister processes and views her relationship with this brother, with whom she has shared a life of mutual dependence since childhood, despite the lack of blood ties.​

​Legal Warning to Harassers:​
Furthermore, this is a warning to certain cyberbullies: ​​Your actions in obtaining personal phone information through illicit channels to conduct harassment have been reported to the police and a case has been officially filed 30 minutes ago.​​ Consider the consequences.

​Final Statement:​
​Only those who have actually seen the content labeled as "LTP" have the standing to comment on / report / criticize it.​​ Conversely, ​​any statements made without seeing it are considered slanderous accusations.​

​Game Feature Descriptions:​

  • ​[Study]​

    • The protagonist (player as the brother) can arrange for the sister to take various lessons.

    • Lessons primarily increase different attributes.

    • Studying consumes ​​in-game currency​​.

  • ​[Social Practice]​

    • The protagonist can arrange for the sister to participate in various social practice activities.

    • This will increase certain attributes and ​​earn in-game currency​​.

    • However, it ​​generates significantly more fatigue​​.

  • ​[Rest]​

    • The protagonist can arrange for the sister to rest at home or go on outings/trips.

    • This ​​reduces the sister's fatigue level​​ and may even ​​increase Affection Points​​.

    • ​Affection Points​​ are a prerequisite for unlocking the best emotional ending.

  • ​[Wardrobe]​

    • The protagonist can choose different outfits for the sister to wear.

    • Changing clothes affects the sister's ​​mood/state​​ while at home, varying depending on the outfit worn.
