Okay so it’s actually a manhwa but there’s this one called bittersour and they remind me so much of my age gap mnsng headcanon where Mnh is a confident older bottom and Jsng is a whiny service top I definitely recommend checking it out! Also I’ve been watching the bl Fool in Love recently and while some parts of it are kinda boring imo it still has that age gap older bottom x younger top theme that I like (just be aware that there is a dub-con scene if that’s something you’re not comfortable with).
