Since the first episode, I've been pulled over and didn't really want to end the episode. I like the fact that they not only showed Sang Tae (the autistic older brother) as an extra character, I especially liked the growth they showed in his character which kind of helped Kim Soo-Hyun's personality grow as well. The relationship between the three of them literally gave me all the emotions, from happiness, adoration (especially when Moon Young and Sang Tae uses to argue kindly), sadness, etc. Big brother's personality growth and realization and trying to act like Big Brother have crazy happy I cry many times. I don't even need to really talk about the amazing chemistry between Kim Soo-Hyun and Seo Ye-ji, but I will because it was so perfect. They both were cute together and every scene they were in showed off their amazing acting skills. Although every drama has a cute scene between the main couple, the small cute scenes between this couple were very different and special because of the characters they portrayed.
They fit in well with their roles, Kim Soo-Hyun has been a gentle yet powerful carer who literally perfected from his demeanor to the way he delivered the dialogues. Same goes for Seo Ye-J's Ko Moon Young, she was so elegant but brave that I loved it. Also, her clothes and styling on this show deserve an award, there wasn't a single outfit she didn't wear. There are a lot of shows that have female leads dressed in amazing clothes but the thing that made me love her character and this show in general, even more than that, is how they explained why they dressed so much and justified it as a coping mechanism, that was really something special. I loved all the stories they did on that show and they were so different from anything I've heard, I swear if it actually came out I'd go buy it now. Right from the start, the relationship between the two brothers has been really commendable, and the actor who plays Sang-Tae really deserves an award for his acting on this show. All in all, it was a great and unique show that everyone should watch. You might think it's a pretty heavy show but it's actually a perfect balance and I guarantee it will make your heart happy and warm in the end and you'll cry happy tears for sure, many times if you're like me haha.
