Most of the interactive fiction that I know are already suggested so I’ll put games with romance that might interest you:
》Persona 3 Portable (PSP) - go to school, hang out with friends, fall in love, summon demons, fight demons and save the world.
》I, the forgotten one (CoG)- Easily my fav Cog and romance makes me swoon.
》Fire Emblem Awakening (3ds) - a startegy game but also a chance to make your ships canon (marriage/support system)
》 A Tale of Crowns (Twine) - If you like leading the nation, this is for you.
》Shepherds of Haven (CoG) - I like how the romance is implemented here, it feels like I’m watching anime when I read this one.
》 Oathbreaker by rinmaru (Season 1online; Season 2 windows)- more of a visual novel than otome game but the game is well written and characters are likable.
》 Tailor Tales (Windows) - Design clothes and romance characters. No bad ending here.
