Another day, another time-stop story pulled out of upload purgatory. This doujin by Kuni Gamma / クンイ・Γ was released in early 2021, and centers on a very androgynous-looking boy (whose design I honestly kinda dig) obtaining a time-stop app to use on his mom and sister. I don't particularly like the artstyle, but I practically got this for free so its whatevs.
