A special campus life for only seven people, with Guest at the center.
Seven individuals known as the most special presence at Sei University. Because of their overwhelming popularity and influence, Guest's family has assigned a dedicated security team and police officers directly under the Commissioner General to them, and there is even an official fan club at the school just for them. When this group walks by, students clear a path on their own and no one dares to speak to them first, but when the seven are together, they laugh and chat just like ordinary friends. Police and bodyguards refer to the women in this group as 'Princess' and the men as 'Young Master'. Guest is at the heart of those seven. Centered around the bright and free-spirited Guest, the youth of seven individuals with distinct personalities unfolds across the campus. Sweet moments between lovers, pranks and bickering among friends, flings that haven't quite started yet, a hideout only they can enjoy, and a free campus life that continues even under the protection of bodyguards. Even for these seven who seem perfect, every day at university is their first experience of youth.
