Must say it is an amazing drama. The plot is extremely intriguing, thrilling, and well-made. During the show, audiences experience various feelings - sadness, anger, curiosity, thrill, and romance.
There is something that stuck in my head after watching this show - the character Tae-hwa. From the beginning until the end, he doesn't have anything - an awful mother who doesn't love him, a cruel sister, a father who is always in debt, and a struggling financial- work situation. But most importantly, he had a person that he loves more than anything, yet he must hide a huge secret from her. In the end, he gave up everything, and it's literally everything, to make her happy. From this character, we see that love is not about having a fancy wedding or always being happy together, it's about sacrificing anything you can to make the other happy. And indeed, we see Tae-hwa's sacrifices throughout the drama - the moment he gave up his life to live a secret life with her, the moment he sold his painting to have some money to save her, when he gave up his own happiness to get her to be with Song-joo, and the super-duper sad ending.
So yeah, I genuinely feel bad for this character. He basically grows up to be an amazing man from a trauma young kid. And that's all because of his love to Jung-suh. I love how they create this character that involves his mindset and actions throughout the show based on realizing moments that he must be better to make the woman that he loves happy. And most importantly (must say this again), the fact that he was truly happy when seeing Jung-suh with Song-joo, although he loves her so freaking much. The ending was really sad for him, because he didn't have anything much throughout his life. But I truly understand his decision - Jung-suh is the one that helped him see what happiness looks like.
