Because this is a Netflix drama, I thought that this would be over the top with a huge budget, so I didn't expect much except for a classic Western plot that was extremely flashy. I didn't expect to love it as much as I did. I really need to stop doubting Netflix's asian drama originals. Yes, it seemed to have a big budget, but not as much as a lot of the original action dramas. It was simple, but the plot was complex, and the relationship between So Yun, Nan Do, and Holo was really solid. So Yun, due to her face blindness, doesn't trust people off the bat, and they always need to earn her trust. Nan Do, was a man who didn't believe in love and really any emotion after his mother's death when he was young. He didn't believe in creating positive relationship with people except for Holo.
It was extremely interesting to see how Holo's existence influenced both So Yun and Nan Do and ultimately became almost a middle man - expressing both So Yun and Nan Do's better emotional traits. He took the best parts of both of them and became this confidant to both of them.
Yes, this drama had a lot of cringy and cheesy Asian drama tropes, but they were easy to look past with everything going on. I think the one I hated the most was how So Yun had thought she was in love with Holo and acted like such an idiot with her imaginary boyfriend. Yes, I have watched My Absolute Boyfriend and have seen a relationship between a robot and a human and totally shipped them, but this one was weird. Holo was such a great influence on So Yun, and he had brought her out of her shell and helped her become confident in herself, but her sudden development of feelings for him was super odd. Even Holo looked extremely uncomfortable while trying to go along with all her date plans. In the beginning, So Yun was a sheltered woman who was great at her job and terrible with starting any kind of relationship. But when she first met Holo, she was quirky, intelligent, and cautious when she needed to be. She just needed a little kick. Then when she fell in love with Holo, she was still all of those things, but it ended up being this cycle where her happiness depended on Holo's existence and him being by her side always. It never seemed healthy. In the middle of the drama, I actually started to dislike So Yun's character, but she came through at the end.
Nan Do was a funny character. Even though he was trying to "teach So Yun as lesson" but ruining her life...all I really saw him as, was a butthead. He was wilding out in the beginning, but when it mattered, he would do the right thing. It took a little while to get out of his ways (with a little help from a crush developing for So Yun), and he expressed some annoying drama tropes, but all in all, it was understandable. Not reasonable, but understandable.

I think my favorite part of this whole drama, even though it was cheesy and obvious, was Holo's "backstory" and who he was and the people who created him, and what they wanted to be. I think the only time I sad cried in this drama, was when So Yun and Nan Do finally realized why Holo's personality was programmed the way it was...because there was a specific reason. Plus, it hit home for me personally understanding how hard it is being the person you want to be, but honestly scared to be that person.
