What is the relationship between fighting fish IU and sweets?

Betta IU and sweets are friends. Tian Tian is just a big brother in the list of IU, and as time goes by, she has become a friend. IU, Betta Fish, the glory of the king anchor, is currently the champion of the double list of the glory of the king Summit, and is known as the first person in the Summit. At present, Yao Yao, whose peak value is 1900, leads, so some disgruntled netizens question that the invited actor is the director of "the glory of the king", which is similar to LOL Nuo Dao. However, the peak of the glory of the king will be a single random ranking, which is different from the original model, so the probability that Betta IU is the strength anchor is much greater.
