If you use the attribute of "lucky mouth" well, it will be a cute attribute. If you use it poorly, it will be a typical "lucky mouth" attribute. For example, it is like making a bowl of chicken soup for the soul and adding a bunch of suspicious objects such as glass shards and Sanlu.
What does it look like when two chatty people come together? After all, it won't be the destruction of the world, right?
It's a story about two people who had a bad conversation and somehow got together (being stupid), maybe.
