I need help remembering a story

Okay so i remember reading this story like a long long time ago like back in 2020 but i can’t seem to remember the name sorry if my grammar isn’t correct because im really desperate rn but from what i remember there’s a girl with pink hair and she is reminiscing about this one time she had sex somewhere (maybe in a hotel or cruise idk) but she haves sex with other people but it’s just not as good as the mysterious man she did it with but the thing is the mysterious guy she did it with is her best friend and they both don’t know that they did it with each other the girl meets strange people she once had a stalker who really liked her and when she gave him a chance he wasn’t good with his dick but he was great with his mouth but the best friend didn’t like him and he told the dude to back off and protected her a lot but they were like bullying with each other playfully he was nonchalant but then the guy had a best friend who was digging the pink hair girl and she thought that the guys best friend was the guy she did it with oh also the guy she did it with (her best friend) had a strange tattoo it was like the sun with a circle or some shit on his leg she remembers it clearly and she saw a peak of the guys best friend tattoo and thought it was him but it wasn’t and she told him to back off but he wouldn’t and her best friend had to step in and protected her again but then she saw his tattoo and found out it was him and boom they got together and sex was good and great and they had a happy ending please someone tell me if they know what I’m talking about because I’m desperate
