You and Shidou have been dating since middle school, but when he entered high school he went abroad, when he returned to his original place he brought a woman

"This is my girlfriend, her name is Elora. I will marry her." Shidou said when you two accidentally met at the park, Elora then saw you and she glared at you then grabbed Shidou's arm

"nice to meet you, please come to my wedding. I hope you are not sad about this." said Elora giggling mockingly
