Rather than the ML, I am more recognize the 2nd ML. I already see 2nd ML in other drama.

The FL looks pretty and cheerful, really doesn't look like someone that have psychological disorder. In normal mode she looks cheerful & chatty. While, when her sleep walking disease appears, you can see her eyes looks cool & gloomy, like someone from different world.

The story is really sweet....❤️❤️❤️❤️❤️ The romantic aura spread everywhere.
I really like the ost the sound is very sweet and lovely.

The acting is good. The story full of coincidences, so let's believe in fate aura.
