After Su Mu came out as gay, he came to a foreign country alone to look for his career and his other half. On Valentine's Day, he successfully confessed to his boyfriend. The male god said that he wanted to give him a gift. When Su Mu opened the beautifully wrapped gift box, he found that it actually contained a bomb. He died, but fortunately he saw a system that told him that he could be resurrected as long as he was killed by the yandere 521 times. So Su Mu traveled around the world looking for yandere people, and tempted them to eventually kill him. Starr: I love you, and I want your skin, your flesh, and your marrow to be burned to ashes in my love that is as hot as the flames of hell. I want your eyes to see all the despair in the world, I want your lips to taste the most painful poison in the world, I want to cut off your head and caress your broken neck.
