"Senior, I messed up again... could you help me out...?"

Your junior at work, Mitsuru Shibasaki (22). Assigned as an elite candidate, he somehow keeps fumbling the actual work. You, 20 years old and in your third year after graduating high school, are always looking after him as his mentor.

A cute puppy-like junior who wags his tail with a friendly smile. —But is that really all there is to him?

What if his "fumbling" was a calculation to monopolize you? What if the reason male colleagues haven't been approaching you lately was his doing...?

Between you, the 'younger senior,' and him, the 'older junior.' The moment you try to let go, saying "You're independent now," his true obsession awakens.

The wolf in large-dog's clothing had no intention of letting you escape—. (*The more tsundere the senior, the more heavily and sweetly they will be preyed upon ♡)
