I don't know where to start. When I watched the first 10 episodes, I thought it would be the best teen series I've ever seen, but then it turned into a really boring drama. The actors acting in the drama is really good. The scene where the ML kisses the FL while she's asleep was terrible for me. Also, it seemed like they were going to make the younger brother fall in love too, but the writer probably realized they were messing things up at the last minute and abandoned that idea. The storyline became worse and started to get boring for me. I ended up skipping through a lot of scenes if you have spare time and enjoy overrated dramas, you might want to give it a try
