It is actually hard to write a review for this show, not because it is particular good nor bad but it is just uninspired. An apt description would be mostly harmless. ;)
There are cute moments, a bit of skinship, the odd tears but basically, it is a lazy wet weekend type of binge. You can cook lunch while the show goes on in the background and you won't miss much.
The OTP is ok, cute enough to carry the show for the most part. Cold ML, fun FL, tick! There are even a 2OTP and a 3OTP but they are all obvious pairings. Lots of tropes are used to no great effect (nor ill effects for that matter). I don't know if the writer is inexperienced or lazy or under time pressure but there is almost no depth to the story. Everything is telegraphed and/or predictable. If someone sneezes then someone will be taking care of the sick one and that advanced their relationship to the next level, etc. A case in point, they threw in the cliché separation of the OTP towards the end of the show. Normally, if I was fully invested in the OTP/plot, I would be annoyed and rolled my eyes. However, in this case, I just sat through it and didn't really mind. It wasn't badly written and it moved the story along towards the final conclusion but it was meh for me.
In the end, the show was like a nicely packaged, clearly labelled meal with cooking instructions. ;) I finished it and "enjoyed" it in a low key, easy-peasy kind of way. Your mileage will differ.
