Stupid Girlfriend with an IQ of 160 (GL)

Xu Xiajia is the kind of person who makes people think she is not smart, and even seems a bit stupid. At least that is what Shen Xuxue, who is three years older than her, thinks so. Xu Xiajia, who works slowly and talks hesitantly, is actually a genius with an IQ of 160? This is completely unacceptable to Shen Xuxue, who has known her since childhood. Moreover, this Xu Xiajia left without saying goodbye when she was in junior high school and disappeared for six or seven years. Resentful Shen Xuxue had subconsciously forgotten about her. However, one day such Xu Xiajia suddenly ran up to Shen Xuxue, who was studying in Kyoto, and said innocently: "Xuxue, we will never be separated again." How could Shen Xuxue, who had been influenced by various conspiracy and calculation stories in Chinese history since childhood, forgive her easily? (Small, hold you steady first, and then see how I take care of you~) It strives to be a contemporary love story in a relaxed and fresh style. The first half is set in a foreign country, and the second half will return to China. Conception:
