This is brought to you by the same author of "My Wife Is From a Thousand Years Ago". "If you could go back in time, what would you do?""I would go to the school entrance and wait for you every day to pursue you shamelessly until you're my girlfriend. What about you?""Hmm... I will definitely carefully wait until I'm twenty-four to get to know you again, then gradually fall in love, then get married, and then ask you this question. I live cautiously because I'm afraid that the butterfly effect will make me lose you."
