Baek Ain is your typical lazy guy.

He graduated from university at age 22 with a random degree he chose out of boredom and stayed single because fate decided so until that event happened.

“What? Where Am I??”

And so, Ain's journey began to end this shitty transmigration cycle.

I just lost myself in the deep and shallow temptation of her.
