Title: Adorable And Impossible
Tatsuya has decided to take a part-time gig teaching graphic design at an art college. He doesn't have a passion for teaching or anything like that, but he needs money to help support the business he wants to start, so he accepts the dreaded task of educating the youth. One such youth he finds himself teaching is a particularly bubbly young adult named Tsumugi. Tsumugi wants to be a fashion designer, but he is often late to class, is quick to play around, and often comes in hungover or buzzed, which doesn't convince Tatsuya that Tsumugi is all that serious about his goals.
That is, until one day, after a class training students on a program that allows people to design things, Tsumugi ends up begging Tatsuya for personal training after hours. While Tatsuya isn't fond of working for free, he can't help being moved by this serious Tsumugi he's never seen before, so they stay after and train on the program together. Once again, Tatsuya is surprised by how serious and diligent Tsumugi is about this. He's really drawn to his student for the first time… until Tsumugi decides to reward him with a sexual favor.
Tatsuya, though he is swept up in the heat of the moment, knows just as well as anybody that this can't happen again, but after the first time, Tsumugi seems to be obsessed with getting him back in bed by any means necessary.
