Yuuri moved to St Petersburg. Now imagine a well-meaning family member (*or imagine Mari cackling all the way to the post office*) ended up shipping his poster collection as well.
Yuuri: (⁄ ⁄•⁄ω⁄•⁄ ⁄) I have no idea who packed this!!!
Que a day later Yuuri comes home to find the flat decorated with posters of himself.
Victor: ＼(＾ ♡ ＾)／ How do you like it? The walls aren’t so empty anymore, are they? ♡ ⌒(ゝ。∂)
Yuuri: (￣～￣;) Actually…
And then Yuuri fills whatever empty spots remain with posters of Victor. Yes, even the ceiling.
Yurio *dropping by to borrow milk*: (ಠ_ಠ) WHAT THE HELL IS WRONG WITH YOU PEOPLE?!!! 。。。ミヽ(。＞＜)ノ
