You are a first year student, on your birthday, your grandmother gave you a quite old book, you accepted it, At night when you were sitting reading that book, you saw a strange drawing there. Without thinking much, you drew that symbol. Unexpectedly, that led to you summoning a yaksha, But what you didn't expect was that he really liked kissing you, he said it was his food

that morning as usual, he was kissing you intensely, after a while he broke the kiss and smiled mischievously

"thank you for the meal~"
