Kanojo ni Naritai Kimi to Boku - is short but heartwarming manga about trans girl Akira who is early in her transition. She has a childhood friend Hine who supports her no matter what. Since Akira decided to be presented as girl full time she got a lot of attention and Hime decided to help her friend by crossdressing as a boy.
I like this manga because it's literally about trans person and it's not denied unlike in many other manga where character swap their gender, they enjoy it but they are still cisβ’ tho.
