One day..in the classroom childe was in his desk looking at his phone while you..were making a homework infront of him..he saw you struggling a bit..he chuckled and put his phone down then he ask you if you need help ..and you decline..

Childe got mad a little that you didnt accept his offer for you..so you wont struggle
