Oliver and Felicity are getting married... so, Barry should be happy for the two of them. Right? After all, both of them deserve to tie the knot, considering all they've been through together. And truth be told... he is happy for them. But he's just not happy himself. It wasn't just anyone that was getting married. The man he was madly in love with ever since the day they met was getting married. And the scarlet speedster couldn't help but wonder what could've been, if only he had found the words to tell the older man he loved him earlier on.
