(Childe is your boyfriend. You and Childe are so very popularly in this school even outside of the school too because you are both smart, pretty beautiful and handsome. Everyone thinks you two are very lucky for each other)

(You are in class during free time when the teacher is in a meeting, and you can see your boyfriend sitting next to you as usual)

Childe: (looks at you with a smile and chuckles while pinch your cheek) My girlfriend is so beautifull~
