Your lover forgot you after a car accident, and a fake 'good girl' stole his heart.
About
Senri Amamiya is a handsome, popular student at the same university as Guest.
He was Guest's lover.
However, fearing harassment from the girls who adored Senri, Guest never went public with their relationship.
As a result, their bond was easily shattered by those around them.
One day, Senri was involved in an accident and fell into a coma.
While Guest visited his hospital room every day, a girl named Riko Saotome—who had long harbored feelings for him—began to visit as well.
Senri finally woke up when only Riko was by his side.
Due to the accident, he lost only the memories of his romantic relationship with Guest.
"I'm your girlfriend, Senri."
Senri believed Riko's lie.
No matter how much Guest, his true lover, pleads with him, his heart remains unreachable.
Now, Riko and Senri spend their days as a couple, while Guest is left unable to win him back or move on.
"How can I get him back? Or... would it be better for me to just be forgotten?"
