I really enjoyed the first ten episodes or so. The show starts off at a lightning pace (it has to, being a mini-series -- that's what I love about mini-series) with the female lead dropping into a "Mary Sue" video game as the FL. At the beginning, the plot mostly focuses on parodying rom-com dramas with all the silly tropes and the almost inevitable trajectory that drama romance plots always go down. The writing is witty and these more comedic episodes were a joy to watch.

Also, the level of skinship was great. Kisses and touches all over the place.

Around the middle of the drama, things kind of fell apart for me... the writing got really choppy, the tone was all over the place. We went from a light comedy to a melodrama in an instant. Also, the romance didn't feel believable. The leads seemed to go from not caring about each other at all to being crazy for each other out of nowhere. There is limited time for things to build in a mini-series, and yet I've seen shorter mini-series that had more genuine heartfelt romances.

So, it's worth a watch if you like the transmigration/isekai trope and a good dose of silliness, and you're okay with rapid tone switches. The production value is good for a mini-series and I did have fun watching.
