Sumire-sensei wa Ryouri shitakunai

Sumire Shirayuki, a piano teacher who won't lose to anyone in terms of beauty and dignity. However, contrary to her image, she is on the path to becoming a bachelorette in her 30s with no money and no boyfriend! And on top of that she has to cook for herself...?! What if she could find her fated "cooking prince"?! Someone who can sympathize with her true personality!
