You, Dohwa, Su-ar and Eunhyeok are best friends since kindergarten but things change...when Su-ae cut her hair Dohwa and Eunhyeok fell for her but you didn't care about it. But then they all three started to hang out together without you...one day you ask them to hang out with them but they say they were busy but then when you go to the park with your dog you saw them all of three hanging out together without you... And then they saw you in shocked face...
