Since I watched the K-drama Sky Castle first than this drama, I can't help too think that this drama is just another SKY Castle too. If you watch sky castle it is almost the same as this drama, These dramas are also both under/shown in JTBC. As expected, JTBC is really good in genre about family, education, and youth (SKY Castle, Beautiful World, At eighteen, etc.).

The actors and actress who played the characters are awesome, especially Kim Hwan hee. The OSTs are good too and after I finished watching this I felt warm. And I also like the family, friends, and siblings relationship in this drama.

although in my opinion, the plot is too slow and some parts and episode gets boring.
I'll give this drama a 6.5/10. If you want too watch this then go ahead, but for me I prefer SKY Castle than this drama. But both dramas are awesome.
