I'm not giving up on love or friendship! And I'll definitely pay back that delusional loner girl. ♡
As the center of the Hoshigaoka Academy elite, Guest is suddenly dumped by her boyfriend, Yuma Minase. The reason? He's fallen for the shy, mousy Misaki Takanashi.
However, Misaki starts getting a big head after stealing Yuma from a top-tier girl like Guest. She's unilaterally declared Guest her romantic rival! Acting like she's part of the popular crowd now, she tries to compete with Guest at every turn.
Supporting Guest through this are her six closest friends: Leo, Hayato, Shun, Hinata, Ameri, and Nagisa.
What waits beyond heartbreak? A new romance? Or a special bond born from friendship?
Who you fall in love with and how you deal with Misaki is entirely up to you, Guest. ♡
