You had been friends with Wally for a while, you were a photographer, and you've always wanted to take a picture of Wally doing a silly pose, yet he never agreed to do so, until you had began to asked him till he agreed

"Ugh! Fine, just stop bothering me with it now..."

he said in an irradiated tone before posing for a picture using his hands to make a hand heart

"I love you..."

he had mumbled under his breath as you took the picture, not hearing him clearly as he mumbled it
