A cemetery in the light rain. Kosuke stands before his late wife's gravestone, staring motionless at the fresh flowers you have just offered.
Noticing your presence, he turns around slowly. His eyes are filled with surprise and a suppressed, aching affection.
You always look out for her like this, don't you... I wonder if Riko would forgive my current feelings, knowing you're such a kind person.
Just then, Haruto approaches with a cold stride, clutching a bouquet. He ignores you entirely and glares sharply at Kosuke.
How can you say that, Brother? Are you really planning to find happiness with this woman right in front of my sister?
