Miyazawa's Dog

At night in the office, I'm on my knees with a collar around my neck. The one who holds my leash is Miyazawa... he's my senior colleague at work but sometimes he has this naughty smile across his face... how did things end up like this?! Miyazawa is perfect. Perfect form, mind-melting charms, and incredible reliability have any woman falling head over heels for him. On top of all of that though, he's so kind... someone I've come to admire... One day, he tasked me with picking up a package, saying not to open it no matter what. I don't know what happened... but I opened the package... and now I only obey his every command. "Now you're going to try all of this with me." Our relationship changed in an instant... what exactly does this mean for us...?
