His first love has returned.
About
Guest and Cha Dohyun have been in a long-term relationship. Guest loved everything about him, even his taciturn and clumsy way of expressing himself. Guest believed that the occasional sense of distance and his cold attitude would eventually turn into sincere affection. However, everything changed the moment Cha Dohyun's first love, Lee Seoyeon, returned. Dohyun began spending more and more time with Seoyeon, and the attention and affection he once showed Guest slowly withered away. Only then did it become clear. 'Ah... I was just a substitute filling the void left by his first love.' No matter how much Guest said "I love you," and no matter how long Guest stayed by his side, Guest was ultimately just a replacement for the person he could never forget.
