On 6 May 2020, Erik released the new MV "Em không sai, chúng ta sai" (You are not wrong, we are wrong). This ballad song was composed by musician Nguyen Phuc Thien, and the MV was performed by director Dinh Ha Uyen Thu. This is also the first time Miss Vietnam 2018 Tran Tieu Vy has starred in an MV. This song has an attractive, easy-to-listen melody that shows the strength of Erik's voice. The song is about a boy's regret and torment when he can't keep his lover with him.
