MC loses all three fiancées to a guy who got transferred to his world by the goddess. It turns out, the goddess had the hots for the MC and decided to make sure to get rid of her 'love rivals' by making them Saints and encouraging them to go after the hero. The last girl resisted but fell as well after the other two girls used drugs on her.

MC offed himself after writing all of this in his diary but does not die. Instead, he meets two other gods that ask him to take revenge on the goddess. Apparently, there were two gods in the world, male and female. One subordinate goddess was after the male god, went to the human world, gathered believers, gained power, turned the male god's wife into the demon lord and became the new goddess.

MC agrees to the two gods' request and they pray for his happiness despite also using him as their weapon.

MC ends up crashing the hero's wedding with the thee ex-fiancées. The goddess also crashed the wedding by saying she'd take MC to the heaven's with her but that made the hero think of MC as the last boss. MC used his borrowed powers to fight the hero's party. Maria tried to defend him but got killed off by the hero. The other two girls were defeated easily by the MC. The goddess tried to escape because she knew MC's powers were bad for her but MC ended up killing her too. MC was about to die, hero gets a power up and was ready for the second round but since MC had already won, he lets himself just getting stabbed by the hero. Maria who had no died yet whispers 'stop'

The two gods obtain the powers and turned the goddess into a plaything for other gods. Then novel went on hiatus.
