I'll pose this as two questions:
1) Do you like having romance present in the games you play?
2) Do you like to incorporate an degree of romance into your own projects?
I'm not anti-romance by any stretch - in fact I'm described as a romantic type - but man, does romance ever elude me in game planning. Many games I play, though, are riddled with little romances. Does anyone else think or feel similarly?
If there's 2 or more major characters, I'll usually have the Disney sort of romance, where they start of as rivals or complacent with each other's company, but it develops bit by bit. if we're lucky, they'll have their first kiss or cuddle by the end game.
Sometimes I'll leave romance as entirely optional content. For example: In Menagerie: Remastered, Fyori and Spooky more or less don't get on at all during the first portion of the game, but gradually Spooky becomes impressed by Fyori, and when Fyori learns more about Spooky she also becomes more warm to him. That's about as far as it goes in the progressive plot arc, however, in the large optional side quest with Captain Crikey's hunt for the hoard of the White Wyrm, Fyori and Spooky discuss it some, and as they end up roped into a large corporate conspiracy, they become closer.
In Perseverance: Adherence, Nola and Pep start out as rivals in a way, but over time as they face challenges together, they become closer. The game will build on this relationship quite a bit as things get more disparate.
In Intelligence, the three friends haven't really developed romantic feelings, but they get through everything thrown at them through their combined might.
Exile, it's unlikely romance will be a thing, since it's based on walking your own path... that said, to compensate, it has charming relationships throughout the game as you asked about also. Bit-time characters can be really entertaining, and it's an opportunity a lot of people don't seem to make use of.
There's the guy and girl in Burger World talking about video games and who's going to be pilot this time. As well as just, not even so much charming as just real conversations between parents and children and even just adults.
The boy refusing to eat his fries, and his father sussing him out by jesting that maybe they'll go for desert. My mother did this to me a lot.
There's a young girl and her mother, and the young girl is eager to go on the 'elevator ride' again, her mother says they have to eat first, when you talk to the mother alone, she says she hopes it stays this way, the elevator ride is free and very safe!
Then there's the two blokes arguing if some guy did a thing or not. Oh god, I really should work on that game again.
