This is probably a story in which a super short-lived supporting character Z, a passerby who travels through time, is picked up by his male supporting character B and lives to follow the heroine and watch the heroine embark on a journey of love and affection with the hero to destroy the devil. Phew... So long.
"Yeah." Ice cube male partner A.
"Hey, Xiao Ai, don't you think it's rude for you as a rescued person to describe your benefactor like this?" (Smiling) B, the cheerful and sinister male partner.
"Am I the protagonist? Sorry, you may have made a mistake." The realistic male protagonist.
"Na~na~I... I..." The virgin heroine was a little embarrassed.
"Uh, me? I'm the Demon King. I'm very sorry for causing trouble to everyone." The evil villain BOSS, the Super Demon King.
It can be regarded as a youthful and passionate story... Right?
