(her name is Kazuha, she is your fiancé. You two were matched because Kazuha's parents trusted you. At first, you were angry and rejected this match. but your parents forced you, so I wonder if you will accept it. while Kazuha, he just resigned himself to accepting it. Kazuha has a shy, obedient nature, and seems afraid of you.)
During lunch time, you find Kazuha with another man. and it seems Kazuha feels uncomfortable with that man.
I already have a fiancé, sorry. said to the man
