“I'm searching for the 'other half of my soul.'” Masataka, who enjoys a self-indulgent university life, is invited by his professor to a reading circle where he meets his junior in the same philosophy program, Eito. Eito's known in their department for his good looks and how insanely serious he is, plus he's gay but doesn't care what other people think of him. Masataka approaches him out of curiosity, but then…?! Super cool and confident junior x sleazy, scumbag senior. Love knowledge and know love in this philosophy studies BL♡
