google lens is helpful for stuff like this if your phone has that it’s jeong sana from suicide boy fandom (ugh) lists it as being by the original author of suicide boy park gee I don’t know if it’s a panel from the series or if it’s just standalone art they did as I’m not familiar with this series sorry the tags on anilist don’t even mention ecchi let alone hentai so if that’s what you meant by research you’ll be sorely disappointed I’m afraid hope that helps
