Xiaohua's lines in the airport and Tangmen's evil laughter

Xiaohua: "I don't know if you really like me." It doesn't matter if you don't answer me, because I have fallen in love with you! " Maybe because I like being called' Christmas tree' by you, I fell in love with you! Even if you hate me, call me an idiot, because I am in love with you! Even if you want to go to Germany, I will wait for you, because I love you very much! "
