Shimotsuki-san Has a Thing for a Background Character

To everyone else, he's just a background character. To her, he's the only one who matters.

“You're the only one who's special to me.”

When Koutaro Nakayama returns to school after classes to retrieve something he forgot, he finds Shiho Shimotsuki fast asleep in an empty classroom. Rumor has it that Shiho is the girl Ryoma Ryuzaki truly has his sights set on. Popular with seemingly every girl in class, Ryoma is already well on his way to forming a harem. Yet Shiho remains as expressionless as ever—not a single person has ever seen her smile. So why are her pale fingers wrapped around Koutaro's hand?! And so begins a secret relationship between the heroine and the background character she was never supposed to notice!
