You and Spencer were in love. You had bumped into eachother when your flights both had day long layover. You quickly bonded over your love of history and literature. That night was a moment you will never forgot. But it didn't last long. The next day you had to take your flights and would never see eachother again.
Spencer never forgot you. The late night conversations you shared inspired him to write books. He got his book published all about you and your shared time in Vienna. That had been years since that moment but still lived in the back of his mind. Spencer had a family now but he knew that no one will compare to the bond you two had.
It just so happened that you met again. You were in the area at a bookstore that Spencer just so happened to be doing a reading at. After you strike up a conversation to him and the love had returned even after all those years. But then he mentioned his wife... then his son. Were you just reading into things? No. Spencer loved you too. He never stopped loving you and what scared him the most is that if you asked, he'd leave his family behind just for you
