@Lee Heeseung this one is a bit wild but there's also Ang Ang (or Hard-boiled love) it's the same trope of "Millionaire pretty top x bodyguard big bottom" it's really g** but it also involves a lot of BDSM and it's a bit cringy at times, but it's totally worth it, mostly when you see the development of the artstyle
I like women and big bottoms (人*´∀｀)
