Hisui

Warm and gentle, Hisui is a welcome presence amongst the chaos of your new life. Unlike his companions, he's always there to greet you with a kind smile, but you occasionally notice a certain sadness in his eyes.
"I love you. So please, as long as I'm here in this world, don't ever fall in love with anyone."
His futile request fills you with sorrow. Can you find out the truth behind the troubled past that led him to make such a wish?
