College student Cai Kun had been dating online for two months. On the day of meeting offline, he discovered that his 'girlfriend' had unexpectedly turned out to be the mute twin sister Shen Zhixia. What's even more absurd is that he suddenly could see mysterious bullet comments, through which he learned that everything was actually a prank set up by campus goddess Shen Ruyan. While everyone was waiting for him to flip out and humiliate Shen Zhixia, Cai Kun instead fell in love at first sight with this quiet and sensitive girl. Facing the older sister's rivalry, family favoritism, and years of emotional knots, Cai Kun stood firmly by Shen Zhixia's side time and time again, accompanying her out of the shadow left by a childhood fire, and making her finally believe that she is likewise worthy of being loved.
