Just days. I assume its because mc is effeminate alr in the first place. U can see in his manerism since chapter 1. So it was easy to pass as a shy woman with pronounced features, keeps to herself, has a husky voice. U will notice it more that his nature is alr soft, and feminine once ml arrives. Their manerism is vastly different, even if mc is not acting.
Yea no worries its really so good. As it goes on, the mc will physically look so obvious. By that point, the ml is just blind tbh. Love is blind literally. I have moments where i just wanna smack him for being an oblivious dumbass cos its so obvious. (Not because of mc’s mannerisms or voice, but physically.)

Is it really that easy for guys to feminise their voice?? I might just be autistic but I've been trying to read this for years but that part just gets to me every time and I cannot take this story seriously help
