Flying knife: Hello. Tomato blushes: Hello. What do you do? Flying knife: You have read a book called "100,000 Why"! I am the author of that book! Tomato blushes: liar! Flying knife: No! I swear to God! Tomato blushes: Hehe, are you going to school or work? Flying knife: Go to school! Tomato blushes: What school? Flying knife: I go to work! Tomato blushes red: going to work? Not bad! Company? Flying knife: No! I'm going to school! Tomato blushes: What? I won't talk to you! Flying knife: OK! Say something else! I want to keep this secret! Tomato blushes: Well, say what? Flying knife: What a nice day today! Tomato blushes: Yes! Flying knife: it's windy and rainy! Tomato blushes red: huh? I feel really tired talking to you! Flying knife: where are you tired? Tomato blushes: brain! Flying knife: impossible! At most, my hands are a little tired! How can the brain be tired? Girl, go to see a doctor! Tomato blushes: I think you should see a doctor! Flying knife: Why should I see a doctor? My mind is clear! Tomato blushes: I think you are sick! Flying knife: How did you know I was sick? How do you know everything about me? Who are you? The fairy sister tomato blushed: I am a fairy grandmother! Flying knife: huh? All right! I decided to kneel at your feet! Kiss your feet! Tomato blushes: Good grandson! Don't be so polite! Flying knife: Before kissing your feet, can I ask you something? Tomato blushes: What's the matter? Flying knife: Can you take some time to wash your feet? There are maggots! Tomato blushes: You ........................................................................................................................................................................., you are so ... rogue! Flying knife: ............................................................................................................................................................................, you are really great! It seems that we are predestined friends! All right! Say something serious Tomato blushes: What can you say seriously? Bah! Flying knife: How can you say that about me? You know, since I realized this, your position in my heart! You know this very well! Tomato blushes: Do we seem to have just met? Flying knife: It's been half an hour! Although it's short! But this time is really full! Right? Tomatoes are blushing: what to make up? See how you bully me: in fact, you know the way! Boys will bully a girl only if they like her! Tomato blushes: Your mouth is very sweet! Flying knife: Hehe! It seems that you finally understand my mind! Tomato blushes: What is your heart? Flying knife: Are some words still so clear? I'm glad you understand! Tomato blushes: Hehe! Flying knife: Really! What I said is true! You should know exactly what you are like in my heart! Tomato blushes: What kind? Flying knife: in my heart, I now feel that other girls are just a pile of garbage except you! Tomato blushes: Don't talk about others like that! I'm not as good as you think! Flying knife: Really! I really think so! You are different from others! They are really like a pile of rubbish! Do you know what you are in my heart? Tomato blushes: What is it? Flying knife: you are two piles!
