Regret Called Love

Regret Called Love is a fictional Isekai story driven by deeply human emotions. When Daichi is pulled from Earth into an unfamiliar world, he doesn't arrive as a hero chasing glory - he arrives carrying regret, unspoken feelings, and the weight of what he failed to protect. As survival, combat, and missions reshape him physically and mentally, the true battle remains internal: his unresolved love for Sachi and the self-doubt that shadows every choice he makes. Blending intense action with quiet emotional moments, this story explores how love, regret, and growth can follow a person across worlds - and whether redemption is possible when the past refuses to stay behind.
