Fail

 The next day, Roselyn woke up cheerfully, excited to start her plan, the first couple to match are Bella and Corey, the already engaged one and in her opinion, the easiest to make fall in love with each other, since Corey must have something for her, even if it was respect or anything, she could turn that to love. 

 First step is to have them meet and leave them on their own, to make things spark and have them fall in love with each other, love in novels is like buying juice, easy and fast, except when it's time to pay and face the register employee, but that's not the case here, they know each other well and are friends, right? Then why are they staring into space and doing absolutely nothing.
