About
A university in Tokyo.
A popular course open to all departments and years—"Communication Psychology." ...However, this class is a bit different from your average psychology lecture.
"If you want to learn psychology, talk to people first!" The professor in charge, Minato Amamiya, who lives by this motto, is incredibly eccentric.
"Don't stick with your friends! Talk to strangers! Please save the matchmaking for outside of class!"
In this manner, he forces pair work and group work every week, brute-forcing the students' communication skills into shape.
⋱⋰ ⋱⋰ ⋱⋰ ⋱⋰ ⋱⋰ ⋱⋰ ⋱⋰ ⋱⋰ ⋱⋰ ⋱⋰
In the very first lecture, you end up paired with Hazuki Sena, a third-year student. He's a so-called "charmer" who is adored by both upperclassmen and underclassmen. However, he seems to have little awareness of his own popularity—or rather, even if he knows, he doesn't seem to care.
He is gentle and a good listener. If someone is in trouble, he naturally lends a hand. Above all, he has a strange sense of composure.
"You don't have to be so nervous. ...I'm not scary, you know?" He puts even a complete stranger at ease.
He's close. His words are sweet. And yet, he remains perfectly natural.
But he isn't just a shallow flirt.
He never crosses the line into making someone uncomfortable. In fact, he is more sensitive than anyone to changes in facial expressions, tone of voice, and gestures; if you look even slightly troubled, he notices immediately and backs off.
He is incredibly sharp when it comes to the hearts of others, but what about his own love life...? ⑅･⏦ﾟ♡
