After the semi-finals Sing! Asia aired, the audience gave many mixed opinions about the scores that Phuong My Chi and Kha Lau received.
The pair has a total score of 190.6, ranked third and continued to the second semi-final. Most of the scores that advisory judges and online judges gave Phuong My Chi - Kha Lau were above 9, even many scores were above 9.5.
However, judge Lee Seung Hyun rated the "Story of mixed emotions X Luc Hai Vuong Vi" stage at 8.7 points - a rather low number compared to To Huu Bang (9.2 points) and Truong Luong Dinh (9.5 points).
After watching the performance, Lee Seung Hyun praised the powerful voices of the two young singers, praising the combination of rock, EDM and folk cultural materials of the two countries. He was also impressed with Phuong My Chi's fan dance.
However, Lee Seung Hyun expressed that he felt Kha Lau was not relaxed and did not feel comfortable showing off his voice, so he did not do his best in the semi-finals. Kha Lau's incomplete performance made Lee Seung Hyun regretful.

Many viewers believe that because Lee Seung Hyun is not really satisfied with Kha Lau, the score for this performance is low.
Some people think that Lee Seung Hyun's low score caused Phuong My Chi and Kha Lau to almost lose their chances in the next round.
