Chapter 1 On my wedding day , I'm up at five , only to find the makeup artist working on my bridesmaid instead of me . ] " Mr. Carter paid extra for me to do an additional bridesmaid look , " she says casually , dabbing foundation on Riley Morgan's face with zero urgency . " Your bridesmaid showed up early and asked me to do her first - said she didn't wanna bother you . " [ ] " Don't worry , Lily ! I'll be done super quick ! " Riley flashes me this sickeningly sweet smile . That's when I notice she's not wearing the bridesmaid dress I picked out for her . Instead , this bitch is wearing white - the exact same color as my wedding dress . [ ] I'm standing there , fury boiling up inside me . ] I whip out my phone and call Mason . " First of all , MY makeup artist is only doing MY face today . " " Second , tell your precious childhood sweetheart to get her ass out of that white dress and into the bridesmaid outfit I picked out for her . NOW . " ] Mason picks up , still half - asleep and sounding resigned . " Come on , Lily , don't be so petty , okay ? " ] " Riley told me the bridesmaid dress you ordered was way too big - it doesn't fit her right . " ] " And about the makeup thing . Riley's such a tomboy , she can't even do her own eyebrows ... " ] I cut him off mid - sentence ] " If you don't agree , this wedding is OFF . " [ ] The line goes dead quiet for what feels like forever . [ ] Mason lets out this heavy sigh , his voice all raspy from sleep . " ... Is it really that serious , babe ? " " Fine , whatever . Happy wife , happy life , right ? Put Riley on the phone - I'll talk to her ." I hand the phone over to Riley . ] The second she picks up , her face goes white as a damn sheet . [ ] Her eyes start welling up with tears . Acting like she's the victim in all this bullshit . " Mason , it's your big day , not mine . I just wanted to look nice for you - how could that possibly be a crime ? " [ ] " Seriously , when did bridesmaids have to look plain on purpose ? Does the bride really feel that threatened just because someone else put on a little makeup ? " [ ] I know damn well she's saying this for my benefit . But I don't even look up . Mason shoved this bridesmaid down my throat - he can deal with th the mess . A week ago , Mason suddenly springs this on me out of nowhere . ] He's got three groomsmen lined up , but I orlly have two bridesmaids . Says I need to find one more ] I'm still trying to figure out who the hell to ask when he just steamrolls right over me with his childhood friend . " Riley grew up with all of us - she's the only girl in our whole crew . " " The other three guys are all groomsmen , but she'd just be sitting there like a regular guest . Makes it seem like we don't give a shit about her . " " You need another bridesmaid anyway , so why not just let her do it ? " Mason says it like it's the most obvious thing in the world . ] Something about it rubs me the wrong way , and I want to say no . ] ] But then he starts with the sweet talk and puppy dog eyes . Laying it on thick until I can't get the " no " out of my throat . So I cave and say yes ] The same night I agreed to this shit , we had our pre - wedding friends hangout . That was the first time I'met Riley Morgan face to face . ] ] No makeup , white t - shirt , jeans - looking all fresh - faced and innocent . When she sees me , she's way too fucking friendly , looping her arm through mine and calling me Lily . " Mason's such a lucky bastard , landing himself a girlfriend as gorgeous as yout " ] " None of us ever liked his exes , but finally he scored a good one . " She's got me on one arm and Mason on the other , pulling us both down to sit . [ ] The whole overly touchy - feely act makes my skin crawl . [ ] " Thanks for letting me be your bridesmaid ! Otherwise these assholes were gonna make me be a groomsman instead ! " ] Ethan , one of Mason's boys , jumps in : " We already had your groomsman suit made ! You're our group's princess - for Mason's wedding , you gotta be front and center " ] " Don't be ridiculous , Lily is the star of the show ! " ] They're all playing off each other like some rehearsed act . ] I can't get a word in [ ] The whole damn party . I'm sitting there like a third wheel They're drinking and playing games , and Mason automatically starts blocking drinks for Riley . When they're all tipsy , Riley hooks her arm'around Mason's neck and they start belting out some sappy song about friendship Getting all emotional and shit . ] " Mason , from now on you won't just be mine anymore ... " ] " Say it ! Tell me we're best friends for life ! " She's shoving the mic in his face , demanding an answer . 1 hit my breaking point , slam down my drink , and storm the hell out . That party triggered a week - long fight between Mason and me . We only made up the day before the wedding . The bridesmaid thing was already set in stone - too late to change it . ] I just want to get through this wedding without any more drama . ] But Riley's still stirring up shit .] ] I'm not taking this crap lying down If today doesn't go exactly how I want it to , this wedding is fucking OFF .
