Noumi Masataka, who’s living the self-indulgent university life, joins a book club after being invited by his professor. There, he meets Tan Eito, an underclassman in the same philosophy department. Eito is serious, openly gay, and utterly unconcerned with other people’s opinions. Combine that with his striking good looks, and Masataka is very much intrigued. He decides to approach Eito, but how will the superconfident junior react to his easygoing senior when they couldn’t be more different?
