My Youth Romantic Comedy Is Wrong, As I Expected, Vol. 11 (light novel) — Wataru Watari

CONFLICT, CHANGE, AND CHOCOLATE At Iroha Isshiki's request, the Service Club is now helping with a Valentine's Day event-and once Miura, Ebina, Kawasaki, and the rest of the “it crowd” are involved, the task spirals into a surprisingly major undertaking. Despite the relative calm, though, there's a sense of dissonance that's becoming increasingly difficult to ignore... and feelings that can't be rationalized away. As much as Hachiman would like to keep his relationships the way they are, something is bound to change.
