After losing her first love due to a traffic accident, Ibuki Sumire transfers to Tokyo. She wanted to escape, to run away from everything that happened. To start over in a place that didn't have him. But a series of clues lead her to investigating the case behind the accident.

There she meets him, the person who helps her move forward. But Sumire quickly learns how alike they are. His cold personality is different than the kindness she is used to. However, he is the only one who understands her feelings.

It keeps going around in circles, like a drop of paint. Round and round - an endless stream of pain and lies. But, that stream ended the moment she laid her eyes on his paintings.

Such rich and vibrant colors, it felt like his emotions exploded. Yet, in the corner of his studio, she found it. The real him, a sakura painting of two people walking hand in hand.

A gentle and sweet feeling, something she has never felt before.
