B2ST held the showcase for their recent comeback at the Cube Entertainment headquarters on July 4.

Doojoon was asked whether he supported and watched Seo Hyun Jin's latest drama 'Oh Hae Young Again,' as he had become acquainted with the actress through 'Let's Eat.' Doojoon answered, "I didn't get the chance to watch 'Oh Hae Young Again' but the members said they watched it. I'm glad that Seo Hyun Jin is doing well." Doojoon also touched upon his acting promotions, saying, "I promised the members something three years ago. That I don't think I'lll be able to do two things at once."

The idol elaborated, "Because B2ST and the drama will both suffer [if I try to do both music and acting at the same time]. I think it's only right to be devoted to the group you're in. If a good opportunity arises after B2ST concludes 'Ribbon' promotions, then I will work at my acting with a grateful heart."
