"Often the tomb contains, without knowing it, two hearts in the same coffin." Koyama feared the moment of your death, the moment when he will have to take your soul and carry it to the afterlife.

It was his job and cycle of life, you will inevitably die... But he doesn't like having to let you die, his heart felt emptier than usual when having to think about it.

With that thought, Koyama made an effort to spend as much time as possible with you.
