Emi Tejima
When Haruna first transferred to her high school and Atsu started liking her, she and all the other girls of the class deeply hated Haruna. She was mad at Haruna because she didn't like Atsu back. When finally everyone in the class realised Macharu and Haruna were a couple, they were all happy. Now Emi and Haruna are best girlfriends and get along great, along with everyone else.
