First I would like to say that despite the title I did like the drama and as it also makes it clear it could be better, and in this review I will try to explain why I think so!

The relationship presented about monos and probes is quite interesting and that is what kept me curious to continue the story. The romance itself is certainly one of the positive points of the story, Go Yoo Han is super direct and from the beginning showed that he would like and stay with Choi Yeon Woo despite the history of the relationship between probe and his monos, and so we see he who theoretically would be the weak end of the rope, the most affected if the relationship between them went wrong, guiding the relationship and breaking the barriers created by Yeon Woo.
What most left me with that taste that could be better is the fact that some points of the universe have not been worked well, of course they talked about monos and probes but how does the rest of society see this possible relationship? are everyone really obsessed? didn't Yeon Woo's parents live well until he died, being in a mono and probe relationship? Why didn't you talk more about the disappearance of Yeon Woo's mother?
And that taste could be resolved if there were more episodes or longer episodes. And it is exactly this duration of the episodes that due to clear cuts and some discontinued scenes that took me away from the immersion provided during the drama.
Overall it is an ok drama, the production is very good if we talk about budget for web dramas, the performances are also acceptable, nothing very exceptional but they are also not horrible. And OST is simply everything in my life!!!
