Would I recommend this? If you're a sucker for romance, want some eye-candy (Jung Hae-in), a realistic storyline and don't mind slow paced dramas, Yes.

One spring night starts off really well. Episode 1 is everything you would want a drama to be and more. As it progresses though, watching it sadly becomes somewhat tiresome. It just drags on and on and on and nothing really interesting happens. Of course there are some tension filled scenes but for the most part, its not all that gripping. But towards the end it picks up again thankfully.

At certain points it was also like 50% dialogue and 50% staring at each other, or the main characters would just be shown looking super sad by themselves. It makes sense though because the slow pace of the drama kinda makes it more realistic but then it's not exactly entertaining. As a result, the rewatch value for this drama is close 0. It took me about 2 months to watch the whole thing, that's how uninterested I was.

The acting was superb though. Everyone did phenomenally well so I don't think any of the actors/actresses could have done that much better to make it a bit less boring.

The music was really good but there were certain episodes where it felt like it was 50% drama and 50% music, that just makes you get sick of the music at times.

Overall I am satisfied with the way things panned out but I kinda wish the time spent showing Yoo Ji-ho and Lee Jeong-in being sad was used to explore other aspects e.g. the complicated and toxic relationship between Lee Seo-in and Nam Si-hoon and/or the fun loving dynamics between Lee Jae-in and Park Young-jae.
