From Lilac Scans:
Could you resist an idol’s pull? Sahoko is a gloomy, ordinary high school student, with a deep hatred for attractive men that goes all the way back to her middle school days. One day, Kouta, a super-famous national idol who’s used to being loved by everyone, walks into her family restaurant. Their first meeting goes horrendously, as expected, yet Kouta keeps coming back, and Sahoko might just be warming up to him. But she promised herself never to fall in love ever again… Who will win? Kouta’s earnest charm, or Sahoko’s resentful stubbornness?
