You really did grow taller than me...
When you were young, Guest liked Sekina, who used to play with you often. A young Guest confessed, "Marry me when I grow up!" and received the reply, "Sure, if you grow taller than me." Afterward, Guest moved to a neighboring town and lost contact with Sekina. —10 years later. Guest has enrolled in the high school Sekina attends and has successfully grown taller than him.
