One Spring Night (2019)

Filmed by the same director, both are realistic thought-provoking series with similar atmosphere.

Both dramas deal around the romance story between a girl and a guy where the guy is not seen as ideal for her. Both dramas are very ascetic and have wonderful background music. Both have a lot of romantic couple moments. Generally they give of the same vibe. The only difference is that there is no age gap between the couples and while in "forbidden flower" the female lead is uprising the male lead, in "one spring night" it is the male lead that is pursuing the female lead

So to be married couple. Complicated relationship. Secret love affair. Male chases female first . Strong female. Nice male lead

So, they are similar in a way that, both FL's are in a committed relationship, either married or towards engagement...and then they suddenly meet the ML...

Only difference I see is that, in LAA, the FL is married, so it is more deep commitment and the ML is married too... on OSN, both ML and FL are not married yet, Plus ML has no significant other...

Similar premise...
Lost is tad more mature and way more emotional than one spring night.... the feeling and the emotions they provoke are kind of same though Lost has some scenes where you won't be able to stop your tears.... I would totally recommend watching both of them...

I felt that Run On depicts picturesque landscapes and somehow even One Spring Night gives off the same vibes when it comes to weather and landscapes.

Also, I really like the contrast in the dramas where Run On shows the beauty of the day especially the morning and One Spring Night makes the dark look pretty and somehow uplifting.

Different setting, not noona romance ..however if you like the vibe of something in the rain and the midnight romance in hagwon you'll feel it in one spring night (same director
and producer or screenwriter I think)

Both feature a couple in their thirties who have mature and respectful attitudes towards relationships. The single parent stigma is addressed throughout each drama and each has well-rounded supporting characters. They have similar pacing and atmosphere.

Both dramas have realistic, natural and healing vibes.
Slow paced
Feeling relaxed while watching.

One Spring Night is similar in the slower pace than usual in telling the story. Both lead couples are adorable and their problems are relatable.

- FL also Han Ji Min
- Both ML are single father
- Kind and warm ML

The similarity in names is just ironic!
Similar feeling. The instant connection, the slow romance, the gazes, and the tension.
Beautiful dramas that focus on the romance, with a similar story.
Similar stories. A wounded man, and a girl in a long committed relationship who's soon to get married. They meet in a similar manner.
Of course OSN has a different quality since it is newer, but Summer Scent has a really good quality given the time it was aired.
Both are slow and quiet dramas.

For life-romance-melodrama lovers.
A pitiful man, wounded by life.
FL in a similar situation where she has a bright future in front of her but she is in love with a man that is retarded in the eyes of society, and he loves her earnestly.
Well-written, well-directed, good music, good side characters...
and GREAT acting.

Both dramas have a sweet, slow romance between the main couple, while there is still a man "hovering" around the female lead, that her parents and society expect her to choose and marry.

They both have pure romance... Not romance based on bluntly expressed lust and physical attraction like most dramas.

Of course some beautiful melodrama too. Beautiful sincere feelings..

And there is a slight similarity in the stories.
