A Pro's Guide to Love Letters With a 100% Success Rate

Hey, have you ever written a love letter? What if you could write one with a 100% guaranteed success rate? As a love confession pro, I convey my feelings to girls I think I have a shot with on the daily. Now, that hasn't always worked, and at one point, I'd received thirteen rejections in a row, but the key is to never give up. Fortunately, one day I discovered a stationary set at the school store that gave off a mysterious aura, and knew my undeniably ominous find was just the tool a love confession professional like myself needed. Sure enough, I was able to write a love letter with a 100% success rate, and the rest is history! Calling all unpopular guys: Confess your love. Confess it like your life depends on it, and never forget to seize your dreams!
