Intro. Min-ari is a famous Thai architect whose business is almost bankrupt. In the past, she was betrayed by her first crush, Soari, who stole her drawings and created a rival company using her work. Devastated, Min-ari almost gave up, until she found an anonymous letter telling her to believe in herself—and that letter saved her career.
In the present, Min-ari hires the talented young Jin-ari, who ends up becoming his support, his inspiration and his emotional confusion. The two create a close and intimate relationship, with tender moments and a kiss that they both pretend didn't happen.
Everything changes when Min-ari discovers that Jin-ari was the one who wrote the letter that changed her life. But before they can own up to their feelings, Soari returns, asking Min-ari to come back to her—and Min-ari finds herself torn between the past that destroyed her and the new love that healed her.
