There's love at first sight and then there's Married at First Sight!

For pop culture fans, Lifetime's long-running reality show has proven season after season that love stories can blossom in some unconventional ways.

But with hard work, dedication and some professional help—hello Pastor Calvin Roberson and Dr. Pepper Schwartz—any couple can have a happy and healthy relationship.

With Valentine's Day right around the corner, we decided to ask our favorite couples from the franchise to write a love letter to their Valentine. Let's just say the results are nothing short of sweet and sincere.

"For couples, think outside of the candy box. Try something that's not necessarily conventional Valentine's Day date night (e.g. roses, chocolates, and a fancy overpriced dinner). Go bowling, roller skating, make a bonfire, try wine-tasting or some new activity you haven't tried together before," Dr. Jessica Griffin shared with E! News exclusively ahead of the big holiday. "Trying new things together can increase your bond and creates special Valentine's Day memories that won't get lost in the same-old, same-old Valentine's Day memories of the past."
