Oh Hyuk and IU have been working together for a collaboration track ''Can't Love You Anymore'', which is set to release on April 7. The two singers, who are born in the same year, have been showing off their close friendship in a cute MV teaser, as well as on social media.
On April 5, Oh Hyuk shared a screenshot from his video chat with IU on Instagram. Among the many netizens who reacted to the post was IU's ex-boyfriend.
Jang Kiha, who's also close with Oh Hyuk, has hit 'like' on Oh Hyuk's friendly post with his ex.
Many believe that Jang Kiha and IU are still maintaining a good hoobae-sunbae relationship after all.
