Hello! I'm looking for a CN Novel. The protagonist is a guy at college level who became the business owner of a mystical shop. I remembered him having to exchange his lifespan with an altar to buy something he needs/wants. His father remarried to a young journalist and is very nosy when it comes to crime scenes. He also has a maid that's like a doll and was described as very gorgeous. He also helped or had a transaction with a butterfly monster. Please help me find it! Thank you!
