Sumire-sensei wa Ryouri Shitakunai

Sumire Shirayuki is a piano teacher who can match anyone when it comes to beauty and grace. However, contrary to her image, she is on the path to becoming a thirty-something spinster with no money and no boyfriend! And on top of that, she can't even cook for herself...?! What if she could find her fated "cooking prince"?! Someone who can sympathize with her true personality!
