Synopsis

Natsuki Haihara is a young man who failed to make his high school debut and is now in his fourth year of college, having endured a terrible high school life. He was about to enter the workforce when he was unexpectedly whisked back in time seven years to just before he started high school! Natsuki is allowed to “redo” his regret-filled high school life, and he uses his prior experiences to successfully become a member of a group of six beautiful boys and girls at the top of the class caste! What’s more, the beautiful girl he once had a crush on, Hikari, was also there. The unconscious high-spec young man starts his second adolescence all over again in real life, a strong, new game school romantic comedy!
