The group H1-KEY heated up Friday night with thrilling energy.

H1-KEY (Seoi, Lina, Hwisa, Yel) appeared on KBS 2TV's 'Music Bank' broadcast on the 4th, performing the title track 'It Was Summer' from their mini album 'Lovestruck.'

In addition, they evoked admiration from the audience with a unique choreography full of refreshing vibes and eye-catching visuals. Particularly, H1-KEY's fully immersed performance made the sultry summer weather forgettable.

'It Was Summer' entered the top 100 charts of major domestic music sites, including Melon, Genie, Bugs, Flo, and Vibe. Shortly after release, it rose into the upper ranks of the Melon Hot 100 chart and continued to rise steadily, demonstrating the potential to enter the top 100 charts. Notably, it is climbing faster than H1-KEY's hit song 'A Rose That Bloomed Between Buildings' (Gun-Sa-Pi-Jang), drawing attention for a possible breakthrough of their own highest ranking.
