I'm looking for this manga that starts with the girl getting dumped by her boyfriend.And she refuses to accept their breakup so she runs away from him so they cant official breakup, And she thinks the reason he wants to breakup with her is because shes not attractive when actually its just that he fell in love with a different girl. Eventually another guy ends up getting her to break him and I think that she ends up becoming a love interest with the other guy. (im not 100% sure I didnt finish it)
