This relationship is more ambiguous.

Many ambiguous relationships begin with the word "* * *". In addition to * * * enjoying food, it is also quite ambiguous for * * * to enjoy a glass of water. The cup for drinking water belongs to personal belongings. When you don't dislike a certain opposite sex and allow him to drink water from your cup, it is also the time when your relationship becomes ambiguous.

When eating with friends of the opposite sex, if they are just ordinary friends of the opposite sex, they will basically eat separately when eating together, and there will be no behaviors such as feeding each other or using tableware.
