There are so many of them out there hell and high water, full volume, dirtiest high, under the green light, honey bear, love shuttle and I can give a whole list but you might like these for starters..
In real like (I am from the UK love) gay partners often switch, my gay friends does that but I think from Korean POV, not many people like reading the real stuff. You see Korea always sells us the dream be it K-pop, K-drama, k everything
