Boy group HIGH4 will begin their activities in Vietnam 1 year after their debut.

They marked this new chapter of their career by featuring in Vietnamese girl group LIME's title track music video, "Take It Slow."

LIME was formed through Vietnam-Korea's collaboration audition project VK-Pop Super Star. The group's 4 members were completely trained in Korea.

Their debut track "Take It Slow" was composed by Kim Do Hoon and PJ. LIME also made their first appearance in Korea's broadcasting through SBS Good Morning and radio show Love World on May 25.

"Take It Slow" music video portrays LIME members meeting K-pop stars HIGH4 in real life and spending a great time together. HIGH4 and LIME will act out various scenes.

Meanwhile, HIGH4 released a Korean/Chinese version of "Not Spring, Love, or Cherry Blossoms" on May 27 and unveiled the jacket image of their 4th single album "Baby Boy." "Baby Boy" will be released on June 4.

"HIGH4's 4th single album 'Baby Boy' will feature powerful and addicting synth and bass. It will be a smooth R&B track different from their previous tracks," explained N.A.P Entertainment.

"HIGH4 will meet with their fans through various broadcasting activities. They will perform 'Not Spring, Love, or Cherry Blossoms' in June and perform in Japan in July and August. They will also perform in Mexico, but the date hasn't been set yet," added N.A.P Entertainment.
