Well, a common feature of a typical romance manhwa is the focus on the emotional journey of the couple. There's usually lots of cute moments, maybe some obstacles they have to overcome together to strengthen their bond. Also, the art style tends to be very appealing, making the characters look charming and the settings dreamy.
I think the ideal protagonist for a manhwa romance could be someone who is brave in facing challenges and shows unwavering loyalty in love. They should have a unique background or story that adds depth to their character and makes the romance more compelling.
For a romance manhwa to be good, it needs a compelling storyline. This could involve obstacles the couple has to overcome or a unique setting. Also, the art style plays a big role in creating the romantic atmosphere.

Well, 'Solo Leveling' also has elements of romance within its manhwa. The story mainly focuses on the protagonist's journey in a dangerous world but there are some romantic undertones in his interactions with certain characters. Also, 'What's Wrong with Secretary Kim' is a great romance manhwa novel where the boss - secretary relationship takes an unexpected romantic turn.
A really good manhwa romance novel is 'Solo Leveling'. Although it has a lot of action elements, the underlying romance between certain characters adds a great touch. Also, 'Orange Marmalade' is a nice pick. It deals with themes of love and acceptance in a unique vampire - human relationship setting.
