Atashi no!

Sinopsis

Akoko and Mitsuki are two childhood friends that are so different, yet they still get along well. What happens when they both catch feelings for the same boy? Of course, they're shaken, but good friends shouldn't fight for a boy... right? (Source: MangaUpdates) ~~ Adapted from the manga series "Atashi No!" (あたしの！) by Koda Momoko (幸田もも子).
