Hi, Venus (had good reviews about how realistic the relationship was, they always communicated, advocated for themselves, etc.)
The Story of Minglan (just keep in mind this is a slowburn and romance is not the main focus)
Seconding awkward potato's recs
Just keep in mind that You Are My Glory has an aerospace focus too..really good romance Ā because they support each other but also grow as individuals
New Life Begins has a bigger focus on sisterhood...the romance between the leads is really cute...the male lead is respectful of her choices and let's her do what she wants without feeling/needing to intervene to save the day like other drama leads do.
