My sister told me about this and now I really want to read it.

It is a yuri manga in which a middle schooler behind to identify as a girl and secretly dress as one "he" is still publically male but is exploring their identity secretly. There is a popular girl in the class who dresses masculine. While dressed femininely the trans girl runs into her and the classmate agrees to keep it secret. The classmate is also exploring her identity wondering if she may actually be a male. The two girls fall in love as girl 1 realizes she is definitely trans and girl 2 realizes she is a girl who enjoys dressing masculine. They are separated but meet back up years later when the trans Girl is living as a woman amd girl 2 moves into her apartment complex or form or somethong. 😕
