"Who asked you to confess your love?"
"My brother"
"If your brother asks you to confess, will you confess?"
"Hmm"
"What did he say?"
"What else can I say? Isn't it just that I like you?"
"Say it again"
"I like you"
"Say it again"
"Sister, I like you."
"Fool, me too."
PS: I really don't know how to write such high-tech stuff as copywriting
