Oakbab, a talented architect, decides to return from Japan to save her family’s firm, Jinta Architect, from the brink of bankruptcy. In order to secure a high-stakes home renovation project, she forms a new team and crosses paths with Rin, an award-winning indie architect who has never worked with any company before. As they begin working together, a deep connection slowly develops between them. But just as things start to fall into place, Mind — Okbab’s first love and the founder of rival firm Mind Space — reappears after a 10-year absence, reigniting old emotions and new professional challenges.
