Seku☆Tsuga

Hikari, an omega working in the nightlife industry, is driven solely by financial gain and views relationships through a strictly transactional lens. When Seiroudou Dan, an alpha salaryman, approaches him to arrange a farewell gift for a departing regular client, Hikari sees only the loss of a lucrative income stream. Desperate to retain his best patron as the man transfers to a new department, Hikari attempts to intercept Seiroudou, but this calculated business maneuver unexpectedly triggers a mutual biological heat between them. The ensuing encounter leads to an unplanned mating bond formed during intercourse, fundamentally altering the dynamic between the two men. While Hikari initially dismisses the situation as a minor complication that does not warrant emotional investment, his pragmatic worldview collides with Seiroudou’s unwavering sincerity. The serious-minded salaryman takes the accidental bond with absolute gravity and immediately proposes marriage, creating a profound conflict between Hikari’s mercenary detachment and his new partner’s earnest devotion. This unexpected union forces the money-focused omega to navigate a relationship built on genuine commitment rather than profit, challenging his long-held beliefs about intimacy and partnership in a world where biology has overridden his carefully constructed boundaries.
