Need help!

Anyone knows this manga where all of the guy's past lovers were invited to his wedding and the mc who was also one of the ex's gets together with another character who was also a past lover of the guy who was getting married hahahahah I'm bad at explaining this.... It was a really cute wholesome manga though I remembered the girl this guy was getting married to was a phsycho~
Oh yeah! I remember one of mc's where idk something like a hairdresser~~ I wanted to read this again but I lost my phone along with my screenshots I just can't remember the title or where I picked it upΣ( ￣□￣||) (￣ε(#￣)Σ
