YuuRook thought...
They're both obsessed with each other and have a collection of pictures of each other. Vil found Rooks stache (he wa a a bit embarrassed about it) and Epel found Yuu's (they happily showed him their other Rook picture collections).
Just them being obsessed with each other but Yuu being soo obvious. Bonus points if they get exited when people ask how many pictures of Rook they took today.
Vil had gifted them a camera as a little thank you gift so they didn't have to use the Ghost camera, so they use the Ghost camera for special occasions. The normal camera is exclusively for taking pictures of Rook.
Rooks collection can fit a suitcase.
Yuu has seven boxes stuffed to the brim.
Rook likes taking pictures that are perfect. Perfect pose, perfect lighting, perfect Yuu being Yuu.
Yuu takes pictures of Rook everytime he does something cute, or he just looks pretty. Which to them is always.
HOHMY GOD I FORGOT YUU IS INTO PHOTOGRAPHY. THIS IS EVERYTHING
