SEOUL -- Singer Kang Daniel dropped a teaser video hinting at his comeback song "2U," four months after he suspended activities due to depression and panic disorder caused by cyberbullying.

The 23-year-old dropped the teaser video for 2U on Friday. 2U is the title song of "CYAN," a mini-album scheduled for release on March 24. The singer's comeback performance will be aired live globally through M2, a music show hosted by Mnet, a cable TV operator, at 8:00 p.m. (1100 GMT) on March 24.

Kang, who debuted solo in July last year, had planned to kick off his solo activities with "TOUCHIN," a single album, in late November. However, a coordinated cyberattack hindered his promotions. His online fan community was filled with malicious content.

Complaining about depression and panic disorder, Kang confessed in an online post in December, about two weeks after the release of TOUCHIN, that he could not carry on with his activities. While keeping himself low-profile, he traveled to Portland to film "Hello Daniel," a cable TV travel documentary that began airing in early March.
