BIGBANG's T.O.P. recently shared his regret at not responding to Goo Hara's final text message to him early this month.

In his Instagram post, T.O.P. shared the last message he received from the former KARA member, who was found dead in her home last Sunday, All Kpop reported.

According to T.O.P., he received a text message last November 5 from Goo Hara, greeting him on his birthday. However, he admitted that he was unable to reply to the text, something he regretted very much after finding out the news of her passing.

"Your final message was a happy birthday message I did not respond to. I am sorry, Hara. Rest in peace in a good place," T.O.P. posted on his Instagram.

He also shared that Hara invited him to watch her recent solo single, Midnight Queen, which she released in Japan.

In his recollection, T.O.P. remembered Goo Hara as a person who had a lot of dreams and a lot of passion for her work and her music. He said that he will always remember his friend as a kind person.

Goo Hara is known to be good friends with BIGBANG members like T.O.P. and G-Dragon. After G-Dragon completed his military service, Hara posted a snap on her Instagram showing the pair together in what appeared to be a studio, Soompi reported. She congratulated G-Dragon upon completing his mandatory service.

This was less than a month before Goo Hara was found dead in her home in Gangnam, Seoul last Sunday.

Police have yet to release the outcome of its investigation, but fans believe that Goo Hara took her own life after attempting to commit suicide in May. Fans also believed that the death of Sulli last October also weighed heavily on Hara's mental health.

Meanwhile, Goo Hara's agency announced that fans would be able to pay their last respects to the former idol at a memorial altar. According to the agency, fans and members of the media can pay tribute to the late singer at St. Mary's Funeral Hall in the Gangnam District starting from 3 p.m. today to midnight on November 27, Metro reported.

"To accommodate the wishes of the family to have a quiet funeral for Hara, the agency said that fans are given a separate venue to pay their respects to the idol."We are overwhelmed with sorrow at having to relay the news of [Goo Hara's] passing to so many people," the agency stated.
