The bubble shadow is sooooo adorable. When Caleb disappeared, I remember the manga where the seme was a popular baseball(?) or soccer(?) player and he got hit by a lightning. Then the uke, who was called "ghost" at school can see the seme who is a ghost. It reminded me of that manga because of the scene where Eiji called for his name and when he kneeled down to the window or balcony.
