Before his rebirth, the protagonist was a second-generation member of the black organization [Chigua]. After his rebirth, he entered the police academy and joined the five-person group. It has a physique that attracts perverted murderers, but its strength is beyond the limit.

The protagonist of the first book is the adopted son of the boss of the wine shop, and he has a good relationship with the group of 5 people. The protagonist of the second book is Gin's sister, a "loli". The protagonist of the third book is also Gin's sister, but she lost her memory when she was a child and was adopted by the Akai family. Believe me, these books are all very beautiful.

These are all books. First, the three books are about two male protagonists. The second one has a female protagonist. I personally highly recommend the first book, which is finished.

Reader note

These books should meet some of your requirements (some of the male protagonists are not from wineries), but I haven't read any of them, so I don't know if they are good or not. You can also look at the group named Ke on the bookshelf, and you should be able to find books you are interested in.

Reader note

Detective Conan's novel is equivalent to a time-travel novel, and there is no female protagonist. I think it is quite interesting, so I personally recommend it. If you like it, you can consider reading it. If you don't like it, don't force it [Please pay attention][Please pay attention][Please pay attention]
