Drowning (H.S. AU)

"They say that good things take time, but really great things happend in the blink of an eye. It took me a long time to make you mine, but it only too a second for me to fall for you. [...] I hope you stay with me for the rest of our lives, because, darling, I've been drowning in your love since the very first day I met you."
