Yonghao (played by Kang Ha-neul), a candidate, has already failed twice in a row. Now, under tremendous pressure, he is preparing for his third exam. Such a routine and dull life made Yonghao feel extremely suffocated. In despair, he thought of his friend Soo Yeon, whom he hadn't been in touch with for a long time. Yonghao, who wanted to know about his friend's recent situation, wrote a letter to Soyeon. To his surprise, he received a reply very soon. In fact, Soo-yeon's situation is much worse than Yong-ho's. Not only did she fail to get into her dream university, but she is also seriously ill now and can only stay at home to recuperate. In fact, it was not Soo-yeon who replied to Young-ho, but Soo-hee (played by Chun Woo-hee), her younger sister, who used her elder sister's identity. Over time, Soo-hee and Young-ho forged a deep friendship through letters, and they both regarded each other as the only hope in their lives.[Collapse]
