Shujinkou no Osananajimi ga, Wakiyaku no Ore ni Guigui Kuru

Kazuki Ishii's world collapses — pushed to the edge of taking his own life — once he is swept into the tangled love affairs of Teruhito Amada, a friend so adored by women that he might as well be the lead of a romance comedy. Then, against all odds, time snaps back to the morning of his high-school entrance ceremony. Given a second chance, Kazuki resolves to stay invisible, make no friends, and coast through a quiet life. Yet somehow Meiko Hikata — Amada's childhood friend, an aloof beauty nicknamed the 'Ice Empress' — starts paying close attention to him.
