Thorough business partners

(1)I have a meal partner
(2)It’s not a friend or a couple
(3)There are restaurants where it’s hard to go alone. For example, a family restaurant, a buffet, or a famous restaurant
(4)When I go to a place like that, I have a partner who goes with me pretending to be my boyfriend. Of course, when he wants, I go with him pretending to be his girlfriend
(5)I rarely talk about anything private
(6)He’s maintaining a thorough business relationship. He doesn’t talk much in the restaurant, and he doesn’t pay for it thoroughly by himself, but he pays for what he ate
(7)I don’t have any friends to go to that kind of place, so I like this partnership very much
(8)But what about the man? He’s still in a business relationship, and he’s never contacted me personally. Does this partner think the same as me
(9)Suddenly, I’m a dog honey, but I thought the opponent was building up to do something about me
(10)This relationship lasted for about a year. We eat together irregularly
(11)But at least once a week, we live in the same neighborhood
(12)Does this friend think of this purely as a dining partnership
(13)Or is there a black heart
