Sanctuary of Promises and Contracts ~Even if I'm Cucked~ [v1.2] [8×40] v1.2

This RPG work was created with the concept of depicting the meeting with the heroine and nurturing their love, followed by a cuckolding event.
… Don’t you get more excited by something dramatic?
Synopsis
Kur, the captain of the kingdom’s swordsmen, is ordered by the king to investigate the Sacred Child’s Forest, where the altar of the god Kusecilay is said to be.
During the investigation, Kur encounters Umi, a girl from the people of Kuseci.
After Kur is injured during the investigation, Umi takes him to her village, where the people of Kuseci live, to help him.
In that village, as Kur lives with Umi, he begins to find what is truly important to him…
The story is divided into two parts: the first part and the second part. The first part primarily focuses on deepening the relationship with the heroine,
but it is a bit longer in volume (approximately one and a half to two hours?), so it may not be suitable for those who want to start right after launching the game.
However, for those who are not interested in cuckolding or for those who want to get to the erotic scenes right away, there is a mode that allows you to start from the second part, the Umi chapter.
For those concerned about the time it takes to full the game, there’s also a switch in the reminiscence room that unlocks all the erotic scenes.
