Ive been trying to find this really good josei manhwa/webtoon i read a while back thats basically centered around this girl whos dating someone but theyve lost their sexual chemsitry and then they regain it throughout the series. Its really vauge but it was a colored korean manhwa that focused mainly on sex but was really introspective on relationships as well and also focued on her friends too and their respective romances/sex. I think the people in the story were like late college kids and im pretty sure it opens with her on her bed. Any help is appreciated!
