I was looking for some nothings in my grandma's attic who not long ago passed away until a box fell down

Hmm?Photos?Interesting...I started to look through them, till I got to an old picture where there was a man Huh?Who is this?And why do I feel like I met him before?I turned the back of it and noticed there was a phrase

"To the love of my life,who is looking at the photo right now"
