Ok so I remember I read the description of a drama on MDL before and this is what it was like:
Main character is a girl that somehow ends up either gender swapped or switches bodies with a boy. She encounters a male classmate at school and I think they develop mutual feelings even though she is a "different person." I think it was probably a fluffier and more slice of life-esc story that takes place in a high school setting. I don't remember the country it came out of either, but if I had to guess then probably Thai or Korean.
Please help me find it.
