I jumped into this without much expectations tbh but it really surprised me . I started enjoying it more with each episode. So the question is whether one should binge watching this?? Answer: YES YOU SHOULD. If you like light hearted stuff.
The story is pretty simple and the subject matter is something which one might have watched or atleast read somewhere. (In my case I read many mangas with this kind of story ). Here the FL accidentally summons a devil lord not devil tbh a bad guy...umm...not a bad guy either. I mean atleast that's what synopsis says. ( He is not had tbh he is more like a smart dude). Seriously unlike other dramas usually ML would take atleast 4-5 episodes to understand the new reality or adapt to a new world but here my goodness he went straight to a place where he would get all the information he needed. LIBRARY!
Hahaha...and in one day or night he read everything from ancient to modern and understood science and all new discoveries. That's... really impressive. I wish I could have that sort of photographic memory. Sigh*

All the decisions ML takes are really smart he is not just handsome man he is rather connvining at times and knows how to deal with FL in his own ways. FL on the other hand is your nerdy sort of naive girl which could irritate few people at times but I forgive that because the actress really did a great job in portraying her character or maybe that type of role just suits her. She is adorable.
I must point out that all the actors here are really good. There are subtle actions which one can pick up if you are into acting and stuff that they have done remarkable job in portraying their emotions. Not for a moment you will think...yeah that is little extra.

Though this show is little weak in writing but what can one expect different from such a typical storyline. I mean anybody can guess what will happen in the following episodes pretty easily. Another thing that I liked was the second leads though there are some issues with their decision making (probably weak writing again) but they are good actors and unlike other dramas where you will see besties of ML and FL are usually ends up being a thing as if its mandatory. Here SL have no such relationships. One more person need special mention that is FL's mother. My goodness she was gorgeous and I still think she should be FL's sister or something not Mother. But well...
As I said I have certain issues with the writing but what irked me most is the writing for FL. She like a pendulum. At times she is portrayed like a strong athelete and after some time she will be like damsel in distress and the next if the scene requires her to be stronger she will again revert back to her strong self. The FL is oscillating between strong and weak and not sticking to her character which is an athelete atleast she can remove her heal from that crack herself...you will know what I mean if you will watch.
Okay now that I have get it out of my chest...this show on the positive end is pretty enjoyable ( not to nitpick about silly things ). It is fluffy light hearted and you will keep on smiling till the end. And if you are into the dramas with beautiful cast then it will definitely be your cup of tea. Overall I did not get bored watching the show for a single moment at least for now. So go watch it and share your thoughts as well.
