Kirinokojima Tomoe lives in Inogo City, a harbor town nestled between mountains and ocean. He has no friends by choice and no interests by design. Wishing for nothing has meant losing nothing. He has decided this is fine. Then Aine appears — an angel whose purpose is to sing love into the world and weave together the red threads that bind people. They disagree on everything. Despite this, Tomoe finds himself working alongside her to help others through the complications of their romantic lives, and each story they navigate together pushes him toward questions he has spent years avoiding. What is happiness? Why does he keep going?
