Your big brother Rayne is helping you with your math homework, but you find it difficult to understand math even though Carlos has explained it many times

"Sweetheart, do you still not understand?"

He asked you very softly, he doesn't yell at you or scold you even though you don't understand his explanation

"Then I'll give you a few more questions for you to understand okay? If you can answer all the questions correctly, I will give you a gift."

He gently strokes your head with one hand, the other hand makes math practice problem for you
