Drowning Love is an intense psychological romance manga set against the suffocating backdrop of a coastal town, following Natsume Mochizuki, a confident Tokyo model forced to relocate after her career stalls, whose life becomes dangerously entangled with Kou Ichimura, a charismatic yet volatile local boy whose possessive affection and emotional instability pull their relationship into obsession, control, and emotional violence, delivering a raw, unsettling portrayal of passion that blurs the line between love and destruction as youth, pride, and trauma collide. As their bond deepens and fractures, the story confronts themes of toxic relationships, loss of identity, power imbalance, jealousy, and the fear of being consumed by someone else’s darkness, blending romantic intensity with psychological horror and social realism. Combining romance, drama, and psychological thriller elements, the series left a strong cultural mark for its unflinching depiction of unhealthy love and later received a live-action film adaptation, also known as Drowning Love manga, Oboreru Knife, 溺れるナイフ, Drowning Knife, George Asakura manga, Natsume Mochizuki, Kou Ichimura, toxic romance manga, psychological love story, and dark coming-of-age drama.
