Hello, i'm kind of new here so I don't know how this works but i'm really desperate to find this manga.

I'm telling from my memory only so I don't know if it's accurate or not.

at the first chapter, I think this girl is from college, and she and her friend were looking through all their old stuff and found an old high school uniform, and the main character decided to wear it and go outside. She gets hit on by a guy, and I guess they went out, and from what I remember they were also some how related with each other, and the main character is keeping her highschool girl persona from him. That's all I remember from it.

thank you, that's all. 🙂)

Are you talking about the manga "Imori 201"?

I think you're talking about Liar x Liar?
