The premise of the meme is simple. Two characters, lovers, have been separated for a time. How long is up to you, as is the reason for the separation. Was it unwilling - an imprisonment, a required journey - or because of a choice one of the characters made? The reason may, of course, color the reunion, and somebody may be pretty miffed, with good reason. Still, the theme is the same: intimacy after being apart.
This meme is mostly geared towards being a smut meme, but nobody will judge you for just doing so heavy fluff.
[While Rey had never lost hope that she'd be reunited with the Resistance after the mess that had taken place in Snoke's throne room, it isn't until she sees Finn come towards her and embrace her that she'd finally felt as though she's back home. Not Jakku; that's just where she had lived in limbo, waiting for a family that she now knows are likely never going to come back for her. Home isn't a place; it's the people by your side.
Finn is her home. That much had been made clear when they'd been reunited on Crait and had held onto one another as though for dear life.
They don't immediately have the chance for a proper reunion, since they'd needed to escape the First Order and Leia needed - deserved - to know everything that had happened. But once she puts all that behind her, she searches for Finn, finding him in the same maintenance bay they'd hid out in together just before meeting Han and Chewbacca. She doesn't know if he's processing some difficult memories of his own or just wants to be alone, and so she approaches gently, stopping by his periphery with a small smile.]
