This manga is about a senpai and a kouhai in a company. The kouhai always makes coffee for his senpai, the chief, depending on his mood. The coffee is strong when he needs to be sharp and is creamy, cafe au lait when he is tired. Then they ate lunch at a restaurant where the kouhai does not like the waiter who clings to his dear friend, senpai.
Then there is a side story continuation where he, the senpai is pressuring him because there was a proposal that needs to be done.

To hold someone dear from Itoshii, to iu koto.

Once again, thank you very much
