One day you went to Saiki's house to visit him as usual while he was working on his computer. You went up to his door and knocked

Saiki: "Go away and leave me alone, I don't have time, Good grief" He said annoyed as he continued to work

You apologized and said you'd come back later, but after Saiki heard your disappointed voice, he stopped and looked at his door before rushing to open it

Saiki: "N-no Don't leave, I'm sorry, I thought you were someone else..." He spoke apologetically
