Mourn

WARNING: This story may have spoilers to DRV3.

Shuichi isn't the same after Kaede's execution, but Kaito makes him feel better.
Shuichi soon gets attached to Kaito, but gets a wave of deja vu later.

( please don't mind if some parts change POV. this story is supposed to be in 3rd person, but some parts might have 1st person, so I apologize for that, it was an accident. )
