Yuuri has a framed photograph of Victor on his table.
At the end of Ep 1, just before Yuuri finds out about the video going viral, there is clearly a framed photograph of Victor right in the middle of Yuuri’s table.
It’s a copy of this poster:
In ep 2, on the very first night that Victor stays over in Hasetsu and tries to sleep with Yuuri, we get a shot of his table and it looks like this:
So… in the days after the video went viral, where he avoided all contact with the outside world by switching off his phone and holing up in his room, he decided it would be a good idea to put in a new photo of Victor. More specifically, a close-up of Victor’s FACE.
Even as he frantically disassembled his Victor shrine, he left behind the framed photo.
Even in Ep 4, the framed photograph is still there, although it’s not clear what’s actually in the frame. (damn you reflective glare)
From these shots, it is obvious that Yuuri has moved the photograph from the middle of the table to left, so that his laptop doesn’t block his view of the photograph. The photograph is now placed prominently to his left with nothing obstructing it. So he can stare at it all he wants.
Ok, he’s looking at his phone in this shot, but it does not negate the fact that his workspace has 1) his laptop 2) his notes 3) A PHOTO OF VICTOR’S FACE.
