Barry and Len's relationship evolves into something beyond nemeses beginning with several very public acts of sexual discovery.

Len gave up on love a long time ago. In the aftermath of the Oculus explosion, when an old flame comes back to haunt him, he just wants something normal to distract him from it all. He never expected that two of his favorite things—a heist and the Scarlet Speedster—could end with him drowning in the very emotion he spurned. OR Rainbow Raider strikes again – Len gets hit with LOVE.

Snart hurt Barry and his friends more than once, so Barry decides to hurt him back to let off some steam. At worst, Barry will get some no-strings-attached sex out of the deal; at best, he'll get Snart to fall in love with him and then break his heart to spite him. What Barry doesn't expect is to fall for Snart in the process.

A new threat was coming to Central Kingdom and Prince Bartholomew Henry Allen needed new alliances to defeat his deadly foe, so when his must trusted advisors propose an arranged marriage with the coldhearted King of the Winter Realm, he agrees feeling it was his responsibility if he wanted to protect his country and family.

A mind controlling Meta bursts onto the scene, bringing chaos and death, yet bringing our favorite hero and villain closer than ever before.

Captain Cold's plan for a bit of fun with his nemesis results in a head wound that leaves him without any memories of who he or The Flash is. As Barry nurses Len back to health, both of them start to hope that he never remembers being Captain Cold as the attraction they feel for each other turns into something more without the pitfalls of being enemies to stand in their way.

Barry, Prince of Central Kingdom agrees to marry Leonard Snart, King of Nevar, also known as the Winter Kingdom, who so happens to be a widower, having lost his first husband Mick Rory not too long ago. This won't stop Barry from trying to melt the icy walls that stand between him and Leonard's heart. WARNING: Slash. Reviews are LOVE and Suggestions are welcome!

Barry is… important. Their fling isn't a fling, it's more than that and right now a part of Len is wondering if he will get the chance to tell that to Barry. Or, there's a Singularity above Central City and the Flash has decided to run into it, meanwhile Captain Cold waits for his return... if he returns... and despite his cool exterior, Leonard Snart is not a very patient person.
