It read:“I hoped that if our time together then went by slowly, I'd feel okay. but I don't think that's the case, and Ungie (IMFACT’s Ungjae) said so too. That it's better to live a less-okay life than live life okay without you.

According to the Cultural Heritage Administration, Buddhists believe that the fate of the deceased's afterlife is determined on the 49th day following the death of the individual.It is also believed that the deceased spends the first 48 days going through trials and that their spirit lingers around in the human world. On the 49th day, the deceased is believed to finally leave the human world and go to the afterlife for reincarnation.Meanwhile, the new memorial for ASTRO's Moonbin will open on June 7 at the Gukcheongsa Temple at Namhansangseong. The new place will be treated as a public memorial for the singer for a longer duration of time.
