The F12 Centre is notorious for having a high rate of bursting espers. Dr. Baek Shi-jin, a diagnostic specialist, is sent there. On his first day on the job, Shi-jin meets Jung Tae-yul, an A-grade guide who deliberately hides his identity under the guise of being an admin employee. “As long as you stop paying special attention to Ham Gun-woo, you’ll be able to get along with everyone.” All Shi-jin wanted to do is repay the favour of Ham Gun-woo, the esper who saved his life ten years ago, but instead, he gets found out by Jung Tae-yul, the guide who is has the highest compatibility with Gun-woo... “Doctor... You’re really using your good looks to get me to come for an examination?” After that, Shi-jin starts to develop subtle feelings for Tae-yul, who keeps running into him like he’s been watching over him, and is the first one to rush to his aid in times of danger... “If it were an actual incident, the Alpha Team will arrive in 60 seconds to protect Doctor.” What kind of ending will Tae-yul and Shi-jin have?
