Otapedia25-sai no Joshikousei


Romance, Ecchi


For some reason, a young high schooler is refusing to attend school. Her aunt, Hana Natori, is way too concerned for her own good and decides to take drastic measures to ensure that her niece doesn’t fail out… The grand plan? To dress up as a high schooler and attend posing as her! Not so surprisingly, her plan is foiled on the very first day of school when the history teacher Okito Kanie discovers her identity. How did he find out and how is she not exposed immediately? Well, as it turns out, Hana and Okito used to attend the same high school together…


25-sai no Joshikousei was first created as a romantic drama web manga by Makana.
