What does it mean to live with regrets for the rest of your life? To die a heroic death before the other person can confess their true feelings; to leave their emotions with nowhere to go; to leave them with a remorse that haunts them forever... Maho, a transmigrator, happened to obtain the System and gained the ability to travel between different timelines. He thought it would let him find happiness, but things didn't turn out as he'd expected. A blonde girl who died in an accident, a gray-haired schoolgirl who leapt from an overpass, a green-haired girl with a split personality, a pink-haired exchange student who couldn't stop thinking about ending her life... Each time, they lost their lives for one reason or another. When they were finally saved, they were left with regrets that would haunt them for the rest of their lives. Maho loves these emotions, even if they cost him his life.
"I love Toyokawa Sachiko's stubbornness. Her proud, conflicted tears are as sweet as honeydew."
"I love Toyokawa Hatsune's meekness. Her timid, insecure expression is unforgettable."
"I love Takamatsu Tomori's eccentricity. Her lonely, bitter sobs are captivating."
"I love all intense emotions, because they make me feel alive."
