I should probably stop watching these 3 hour long kdrama movies. It seems like they all (at least the ones I've seen) have the same 2 minute long happy ending. One of the main reasons I still watch kdramas is that they often have long & satisfying endings. This despite being only 3 hours long felt a bit draggy & yet we've still gotten the usual 2 minute ending!

If I ignore the ending thing, this drama is alright to watch, at least if there is nothing else in your backlog. The OTP interactions were quite cute, though highly unrealistic for a friends to lovers romance.
In this genre the chemistry between the leads is key, but I feel that could've been better. The plot is alright, though there is no innovation here, none whatsoever.

There is a love triangle, but luckily there was no time to develop that, so it fizzled out without becoming offensive.

Also the OST is quite nice, however it's strangely underutilized. It's like they went ahead and commissioned some great tunes, but the mixing/editing in the drama is not taking full use of them. Just listen to the OST separately on YT & you'll know what I mean..

The picture is very nice, the cinematographer did a great job.

Speaking of 3 hour long kdrama movies. You Drive Me Crazy (https://mydramalist.com/28300-you-drive-me-crazy) is a very similar story with an extremely similar plot sequencing, but it's like 10 times more exciting.
