Kuro to Kin no Akanai Kagi.

Katagiri Hikikomori Kanade slept in her room most of the time. Her strong imagination, which frequently results in a variety of bizarre delusions, is her expertise. In her dream one night, a strange cowboy man claimed to be the hero of her heart. Kanade was inspired by him to attempt getting a haircut the next day. She then encountered a mysterious man who gave her a haircut in the park, giving her the confidence to go back to school. After getting her hair cut, a man approaches Kanade who turns out to be Sudou Yukio, a former classmate. He was glad to see Kanade again because she used to like him back then. Kanade resides with Sonomura Ikuto, her unrelated brother. Ikuto had warned Kanade not to go hunting for the enigmatic man who had cut her hair the day before. When she came across him in the park, he identified himself as Hasui Tomoomi. He runs the nearby Azalea salon and is a licensed hairdresser. Kanade's homeroom teacher, Konno Chihiro, offered to assist her with her coursework since she had missed so much class. What will now happen to Kanade's life with these males around her?
