Not even faking it tbh. She WAS a tomboy growing up, she just eventually got into girly things as she got older. If you think about it, when she's with him she's also just being herself, the only thing she's actually changing is her attire to be more boyish when around him. That and talking more like a boy, I'm assuming when she's with him she probably uses boku and when she's at her own school she uses watashi.
I have bookmarked this manga for a long time and I am just shocked its still in 21 chapters. is this the latest chapter or are there load of chapters that weren't translated yet?
Please I hope this wholesome story will not get twisted I really like it so far but who even is this guy is he trying to rizz up my boy mc's girl, he don't even know a damn thing about the mc and he have a confidence to say that. I hope the fmc don't take that seriously.
