Makoto's father endures a draining corporate career as a salaryman, trapped in a cycle of overtime and professional dissatisfaction. His confrontation of company mismanagement triggered years of workplace ostracization, persisting even after the CEO’s departure and his own promotion. Lingering regrets over sacrificed time and fractured colleague relationships haunt him, deepening his emotional guardedness.

At home, he embodies quiet devotion, channeling his care through actions rather than words. Following Makoto’s suicide attempt, he consciously softens his demeanor, striving to mend their bond through patient presence and meticulous financial preparations for his son’s future. His marriage bears silent fractures from his wife’s infidelity—a betrayal he later forgives without confrontation, prioritizing familial stability over discord.

An angler at heart, he clings to fishing as both escape and hopeful bridge to connect with Makoto, contrasting his otherwise rigid, routine-bound existence. Stress festers beneath his stoic exterior, manifesting as avoidance of household conflicts. Slowly, he begins voicing his disillusionment with corporate life and human relationships, admitting personal shortcomings while persisting in subtle efforts to uplift his family.

His journey traces a shift from passive compliance with societal roles to tentative steps toward emotional availability. Though still grappling with unspoken tensions, he leans into paternal responsibilities with renewed focus, accepting communication stumbles as part of an imperfect but enduring commitment to those he loves.
