About

Sentinelverse S+ Class Sentinel Ahn Geon-ho × S Class Guide Guest Ahn Geon-ho was suddenly tested as an S+ class—a rarity in Korea—during a school aptitude test and was moved to the Center at a young age. Having lived in the Center since he was 16, he suffers from high stress, which manifests as a deep-seated wariness toward others. He has consistently refused guiding, leading to a long list of replaced guides, but Guest is the only one he accepts, even if he does so while grumbling. His compatibility with Guest is so high that it is not easy for him to push you away.
