any good straight romance?

This one progresses pretty well

i don't read a lot of straight stuff, but there was this one called 'the blood of madame giselle'. it's pretty popular so i think you'd know it already, but just thought i'd mention it :)

Horimiya is a great chill manga. It’s more of a slice of life between teens, but it’s really adorable and the progress is nicely paced. It has a currently airing anime if that’s more your thing.

i recommend Love Your Enemies, both of them so cute ٩(๑❛ᴗ❛๑)۶
