Argh!!!!!!!! This is one of the most commonly used and Cliché things on Wattpad. It's always that the MC gets cheated on by her boyfriend. Her boyfriend cheats on her with another guy's girl friend who turns out to be the bad boy's girlfriend and then they both plot revenge. They fake a relationship to get back at them and while faking it, they begin to fall for each other and blah blah blah. It's too common and it's honestly getting cringe-worthy and is horribly unoriginal. For example :
" Let's make a deal," I began " Why don't you pretend to be my boyfriend while I pretend to be your girlfriend? Deal?"
HE contemplated deeply for a second, his eye brows scrunched " Deal." "
Me : Mama Mia! Here we go again.
