Yes, 'Me Before You' is somewhat similar. It explores the relationship between two very different people and how they change each other's lives. The emotional journey of the characters is a key aspect, just like in 'Listen to the Marriage'.
You could also consider 'Outlander'. It has a complex relationship at its core. The characters face various challenges and their relationship deepens over time, which is similar to the relationship development in 'Listen to the Marriage'. The historical backdrop in 'Outlander' adds an extra layer of depth to the relationship story.
One more is 'The Rosie Project'. The protagonist's journey in finding love and dealing with unexpected emotions in a relationship can be compared to the relationship development in 'Listen to the Marriage'. In both, there are unique characters with their own quirks coming together in a relationship.
A similar novel is 'When Gravity Fails' by George Alec Effinger. It's set in a future Middle East where body modification and virtual reality are common, much like the tech - heavy world of Shadowrun. Another is 'Mona Lisa Overdrive' by William Gibson. It continues the exploration of a high - tech future with a focus on cybernetic enhancements and the seedy underbelly of society, which Shadowrun also does. 'Synners' by Pat Cadigan is also in the same ballpark, with its look at the impact of technology on art and culture in a future setting.
You might like 'The Hating Game'. It has a similar dynamic where two characters are initially at odds but then develop a deeper relationship, much like in 'Listen to the Marriage'.
You can listen to the audio novel of Marriage Therapist on the audio novel website. The novel was broadcasted by Nostalgia Captain, and the content revolved around the story of Qi Yanrong, a divorced female counselor who returned from America and opened a Midway Island marriage therapy institution. The beautiful doctor Ye Fengqin, who had fallen out of love, and Tu Baiyao, the former overbearing president, joined the story one after another. The specific online listening platform could be found on the audio novel website.
They can be quite different. Comics cover a wide range of genres and themes, while BL often focuses specifically on romantic relationships between male characters.
I'd suggest 'Clannad'. It shares elements of heartfelt storytelling and explores various emotions, similar to what you find in 'The Promise'. There are touching moments and character arcs that might strike a chord if you enjoyed 'The Promise'.
Well, 'The Vampire Diaries' manga could be comparable. It shares the theme of vampire love and drama that Twilight is known for. Also, the character dynamics and emotional conflicts have some similarities.
I think 'Blue Period' could be similar. It also focuses on personal growth and relationships with a touch of emotional depth.
You could check out 'Sword Art Online'. Both it and 'Gamer' have elements of gaming, adventure, and character growth in a virtual setting. However, they also have their own unique twists and differences.
One manga that comes to mind is 'Neon Genesis Evangelion: The Shinji Ikari Raising Project'. It shares some similarities in themes and style with the original Evangelion.
I think 'No Man's Sky' manga has some similarities. It features exploration and building elements like Minecraft.
