What was the unluckiest thing in Sue's life? Can you imagine the feeling of a man who isn't gay and straight and suddenly loses his footing one day?

Su Gu was good-looking, his skin was white and tender, and he wasn't a mother. But he still didn't have a girlfriend even at 28. He was a real virgin, and his home was tight. Even if he said he wasn't in a hurry, it would still be a lie. Heh, his bad friend even gave him a rotten idea. It would be good if he liked her. Men are not bad, but women do not love her. Alright, he mustered his courage and ran over to give it a try, but... Alright, let's stop talking. Afterwards, while the other party wasn't awake, he covered his butt and ran away uneasily. It didn't matter if he told himself that he was a man, he wouldn't get pregnant anyway, and he wouldn't lose anything. After calming himself down, he forgot what he had to do that night. But why had he been followed ever since that night?

I'm kinda interested with the synopsis
