Yurushite Want You

The first two chapters are on an ex-delinquent's crush on his colleague (the same pair on the cover).

Next up: a guy who is overly protective of his younger sister especially when it comes to her male tutor. He begins to stalk him in an effort to suss out his weakness.

Chapter 4 is the story of a repeat student who gets dumped after being accused of being frigid as he's never had an orgasm from sex.

In chapter 5 (with some supernatural elements), a waiter has been observing a frequent customer who comes in with thick stacks of books and sits motionlessly for long periods of time. On a impulse, he befriends him only to find out that he's a genius, unlike him who had only completed high school education.

A little tale of a guy with a colleague who sexually harasses him with hugs and gropes in the final two chapters concludes this volume.
