Dimensional Restaurant with All System

The character is the same as my other novel, and the cover of this fanfic is his look. The name will be different though. It's just for fun, and if you don't like it, then suck it. No harem though. Now for the synopsis -- He was living a fulfilling life till old age until his wife died early. he died due to old age and a little lonely. Unexpected to him, He met OAA. -- The cover is not mine and please don't judge me. I just like his look as my character ok? I am tired of some handsome Male lead.
