Mutsuki Chisa♀

Chisa is a class president of Momiji's and Nanana's class. Her parents run a hospital, and that is why she too wants to become a great nurse one day. She works very hard not just to develop her own skills, but to also keep the entire class in line to accomplish their shared goal. However, serving as the shining example has left Chisa isolated and lonely. She has been attending all-girls schools all these years, and she has never had a boyfriend before hence why she desires to fall in love this year. Her new substitute teacher, Nakagawa Shinobu, just might prove out to be the perfect kind of guy that she was looking for.
