Takane no Hana-san

She is a beautiful, smart, and perfect girl. But she shuts out all personal relationships with the other employees, earning her the nickname of the "unattainable flower." The rumor is that she must be dating an "amazing guy." However, the real problem is that she is more like a fifth-grader when it comes to love! She is a clumsy but pure-hearted girl who has a crush on a junior employee, Yowaki! When will flowers finally bloom in Hana-san's love life? (Source: Pixiv Comic, translated)
