Yoshio Tanaka gets reincarnated into a fantasy game world, with healing magic as a "cheat" ability.

A child who was treated like a dog and trained in my childhood has reappeared as a subordinate. No matter how much I push him away, Shin Geonwoo, with his gentle, dog-like eyes, constantly gets on my nerves."I remember your scent. Your scent is still sweet, Team Leader.""What do you want from me? Just leave me alone.""Keep me by your side, like before. I've been waiting for you for a long time."
