Hikari Tsutsui

Hikari Tsutsui is a third-year high school student who has long taken refuge in the world of 2D anime, keeping real-life girls at arm's length. Everything changes when a tardy slip lands him on pool-cleaning duty alongside Igarashi Iroha—the school's most admired beauty—who unexpectedly confesses her feelings for him on the spot. What follows is a six-month real-world romance that pushes Hikari to confront his deep-seated social anxiety and chronic self-doubt, gradually transforming him from an isolated loner into someone capable of forging honest, meaningful connections with others.
