Missing (Two)

"You're kidding me, Allen! My sister is just seventeen!" Seth glared at Allen. He scolded, "You are five years older than us!" 

Allen didn't pay attention to what Seth told him. He made a solemn expression on his face when he replied. "Is love supposed to have an age gap? Even your family status does not matter whether it did not match mine."

"Then why are you often teasing my sister?" Seth pretends to be a strict brother, even though he is excited about hearing what Allen likes about his innocent sister. Or maybe because his sister was one, the reason Allen likes her, thought Seth.

Allen peered meaningfully at Seth. He then confessed, "I've liked her for a long time. And I'm serious when I say I want to marry her."

Seth almost believes in Allen, but there is no way he would give in already, so he insists, "But she is just a minor!"

"Of course, I will only pursue her after you two finish High School," said Allen in a dignified manner.
