I was stuck in a dungeon explosion while working so hard that I actually died.

But when I opened my eyes, I was back to the time of 3 years ago!

Well, I will live differently in this life. Salary is goodbye to s*ave life. I quit immediately and set up a cafe in the store my grandmother left behind.

There are no customers because she is right in front of a dungeon, but it doesn’t matter. All I want is to work two days and play five days. But.

Also, the attractive regular customer who keeps bothering me is somehow unusual.

It doesn’t feel good. Isn’t it like the story of the main character of the RPG, who was just trying to run an errand, and ends up fighting the devil after getting caught up in something annoying?

Yes, I will not. I can not. I have no intention of playing more than the role of a novice innkeeper.”

“Stop following me!” Asher yelled, his patience running thin. He had let it slide for too long because she had done a lot for him. But now she was everywhere, suffocating him.“I’m only trying to protect you,” she responded.Asher sighed, running a hand through his hair. “I need some space, alright? I can take care of myself.”She didn’t budge, and just kept staring at him with that same obsessive look, like she had no intention of leaving.“Is it because you’re strong now? Are you going to leave me because I'm no use to you anymore?” Her voice had turned cold, sharp enough to cut through the silence.“Of course not, you know that’s not the reason…”“Then why do you want me to stop following you?”“I’m just going to the restroom, for God’s sake!” He massaged his temple, clearly at his wit’s end.“Oh, you should have said that earlier.” She giggled, the earlier tension melting away.“I did,” he sighed in defeat.

Our protagonist Caam is a man from Earth that was reincarnated into this world as a demon. In order to survive, he spared no effort in avoiding the sparks of battle and without noticing it, he became strong himself.
