Really sweet story. Hideto is secretly making Yuugen get closer to his classmates through the unfiinished tasks he needs to do to move on. So beautiful. Moving thoughts on living and regrets of those dying/dead, on enjoying the small beauties in life before us.
It's so sad that Hideto truly died and moved on at the end of the story. He and Yuugen had unvoiced feelings for each other before his death and they only confessed while he was a ghost TT__TT
