Haru Kaidou, the oldest son in the Kaidou family, rushes to Canada after hearing his mother is terminally ill and might not have much time left. However, upon arriving, he finds out it's not true. His mother's real plan was to entrust her adopted son, Ren, to Haru's care.

Ren is a boy who keeps to himself, making it hard for Haru to connect with his new adopted brother at first. But as they spend time together during the summer, Haru slowly builds a connection with Ren. He even makes a promise to Ren that they'll live together in Japan once he finishes high school.

Tragically, a severe accident leaves Haru with no memory of that summer or the promise he made to Ren.

Five years later, Ren shows up in Tokyo, hoping Haru will remember his promise. But to Haru, Ren is just a stranger claiming to be his brother. The story unfolds around the question: what will become of the relationship between these two adopted brothers?
