tryna find this one, requesting help

So it was a webtoon I think about mc that was forced to take medicine to appear as a guy, got kicked out eventually after lots of abuse/trauma. Its kind of a harem but more of a found family trope, with like five or so characters that are connected to mc due to like, idk a past life or smth?? There was a old man, a fairy, a knight, and a couple others. Last I remember mc was trapped in this murder mystery mansion basically?
